Poem

🐰
I hopped through /app and sniffed each bit,
Found 777 crumbs where dangers sit.
I planned safe fixes, dry-runs in tow,
Suggested perms so systems grow.
Hop on—let no naughty chmod roam!

Fix all issues with AI Agents 🤖
In @tools/permission-auditor/demos/showcase.py:
- Around line 84-91: The bare except in the JSON parsing block swallows all
exceptions; change it to catch json.JSONDecodeError (e.g., "except
json.JSONDecodeError as e") and print the error message and the offending output
(referencing result.stdout and parsed) so parsing failures are visible; if you
also want to surface unexpected issues, add a separate "except Exception as e"
that logs the exception and re-raises KeyboardInterrupt/SystemExit if detected,
rather than using a bare except.

In @tools/permission-auditor/examples/advanced.Dockerfile:
- Around line 69-73: The Dockerfile creates a real setuid-root binary
(/app/scripts/suid_test) by compiling /app/test_suid.c and setting chmod 4755,
which is a real privilege escalation risk; replace this with a safe test
artifact: do not compile or install a binary that spawns a shell—either create a
non-executable placeholder file or a harmless dummy executable (e.g., touch
/app/scripts/suid_test and set benign content) or simply touch a file and set
the mode to mimic detection (chmod 4755 on a non-functional placeholder) so the
permission-auditor can detect the pattern without introducing an exploitable
program.
- Around line 32-35: The Dockerfile copies Python packages into /root/.local and
sets PATH/PYTHONPATH to /root/.local, which will be inaccessible to the non-root
runtime user appuser; change the build step to install packages into a shared
location (e.g., /opt/.local or system site-packages) or chown the copied
/root/.local to appuser and update PATH/PYTHONPATH to that location so appuser
can run them; specifically adjust the COPY/ENV lines that reference /root/.local
and ensure the build used pip install --user is replaced or mirrored to a
directory owned by appuser (or use pip install --target /opt/.local) and update
PATH and PYTHONPATH accordingly.
- Around line 81-84: The COPY and RUN that install and chmod
docker-entrypoint.sh are placed after the USER appuser switch so they fail as a
non-root user; move the COPY --chown=appuser:appgroup docker-entrypoint.sh
/usr/local/bin/ and the RUN chmod +x /usr/local/bin/docker-entrypoint.sh lines
to before the USER appuser directive (you can keep ENTRYPOINT
["docker-entrypoint.sh"] where it is), ensuring the file is owned and executable
as intended.

In @tools/permission-auditor/README.md:
- Around line 43-49: Update the README clone instructions to reference the
repository in this organization instead of the external URL: replace the git
clone URL `https://github.com/altynai9128/permission-auditor2.git` with
`https://github.com/cortexlinux/cortex.git`, and update the subsequent
navigation step to `cd cortex/tools/permission-auditor/`; alternatively, remove
the clone step and add instructions to run the tool in-place from the
checked-out monorepo (e.g., `cd tools/permission-auditor && python3
src/auditor.py`) so users know the correct path within this repository.

In @tools/permission-auditor/scripts/demo.sh:
- Line 13: The script performs cd "$DEMO_DIR" without checking success; update
demo.sh to ensure the directory change succeeds by adding explicit error
handling after the cd (e.g., check the exit status and print a clear error
including DEMO_DIR and exit non‑zero) or enable a fail-fast mode at the top of
the script so failures abort immediately; make the change around the cd
"$DEMO_DIR" line in demo.sh and ensure any subsequent commands only run if the
cd succeeded.

In @tools/permission-auditor/scripts/docker-entrypoint.sh:
- Around line 6-13: The script uses unquoted $HOST_UID and $HOST_GID and doesn't
validate them; update the conditional and commands to quote variables (e.g.,
"$HOST_UID", "$HOST_GID") and validate they are numeric before running
usermod/groupmod/chown to avoid injection or word-splitting. Specifically,
change the if to check non-empty quoted values and add a numeric check like [[
"$HOST_UID" =~ ^[0-9]+$ ]] && [[ "$HOST_GID" =~ ^[0-9]+$ ]] before calling sudo
usermod -u "$HOST_UID" appuser, sudo groupmod -g "$HOST_GID" appgroup and sudo
chown -R "$HOST_UID":"$HOST_GID" /app; if validation fails, emit a clear warning
and skip the remapping. Ensure error handling remains (capture failures and log
warnings) but use the quoted variables everywhere.

In @tools/permission-auditor/scripts/install.sh:
- Around line 29-31: The install.sh script uses a relative path
"../src/auditor.py" which fails if the script is invoked from a different
working directory; update install.sh to resolve its own directory (use
${BASH_SOURCE[0]} or similar to compute script_dir) and use
script_dir/../src/auditor.py as the source for the copy to
/usr/local/bin/perm-audit, then keep the sudo chmod +x /usr/local/bin/perm-audit
step; reference the existing ../src/auditor.py string and the perm-audit target
when making the change.

In @tools/permission-auditor/src/auditor.py:
- Around line 35-62: The load_config function references undefined symbols
EXCLUDE_PATHS and Colors and is never invoked; move the entire load_config
definition to appear after the Colors class and the EXCLUDE_PATHS constant so
those names are defined before use, and then call load_config(...) from main()
(replace any inline default config use in main with the returned config) so the
function is actually used; alternatively, if you prefer not to move it, update
load_config to avoid direct references to EXCLUDE_PATHS and Colors (use literals
or defer resolution) and add a call to load_config in main() to load and apply
configuration.
- Around line 1212-1214: The code mistakenly performs a self-import ("from
auditor import apply_selected_fixes") from inside the same module which will
raise ImportError; remove that import statement and call the local function
apply_selected_fixes(all_findings, indices, dry_run=True) directly (ensure the
apply_selected_fixes function defined earlier in the file is available).
- Around line 32-33: The file contains duplicate imports of json and Path (the
symbols json and Path are imported twice); remove the repeated import lines
shown in this diff (the second "import json" and "from pathlib import Path") so
each symbol is imported only once, and verify there are no other duplicate
import statements for json or Path elsewhere in auditor.py.
- Around line 679-680: Replace the bare "except:" blocks at the three try/except
sites (around lines 391, 679, and 705) with a proper exception handler that
catches Exception only (e.g., "except Exception as e:") and log the error (using
the module's logger/audit logger via logger.exception or logger.error with the
exception) instead of silently passing; ensure you do not swallow
SystemExit/KeyboardInterrupt by not catching BaseException and, where the
original intent was to ignore recoverable errors, explicitly handle or comment
why the exception is safe to ignore.

In @tools/permission-auditor/src/auditor.py.save:
- Around line 277-278: The line merges a comment and code causing a SyntaxError;
split them into two lines so the comment stands alone and the conditional
executes: place the comment "# Skip excluded paths" on its own line, then add
"if should_skip_path(current_path):" on the next line followed by the indented
"return". Ensure indentation matches surrounding block and references the
existing should_skip_path and current_path variables.
- Around line 1-14: Remove the editor backup file auditor.py.save from the repo
and stop tracking such backups: delete auditor.py.save (or run git rm --cached
auditor.py.save if you need to preserve it locally), add the pattern *.save to
.gitignore to prevent future backups from being committed, and commit the
changes; ensure the canonical auditor.py (without .save) remains in place if
that is the intended source file.

In @tools/permission-auditor/test_permissions/check_perms.py:
- Around line 1-4: Add a module-level docstring at the top of this script
describing its purpose as a permission-auditing diagnostic utility (what it
checks, expected inputs/outputs, and any important behavior), placed immediately
after the shebang and before the imports; ensure the docstring is a proper
triple-quoted string and concise so the module complies with the "docstrings
required for all public APIs" guideline.

In @tools/permission-auditor/tests/integration_test.py:
- Around line 36-59: The test_world_writable function is missing a return type
hint and contains unreachable code after the finally block; add a return type
annotation (def test_world_writable() -> bool:) and remove the dead print/return
lines following the finally so the function ends after the cleanup/unlink in
finally and the intended return True/False remains inside the try/except/logic;
locate and update the function named test_world_writable accordingly.
- Around line 9-34: The test_777_file function lacks a return type hint and
contains unreachable dead code at the end; update the signature to include a
return type (def test_777_file() -> bool:) and remove the trailing unreachable
print("❌ test_777_file: FAILED") and return False lines, and ensure all control
paths return a bool (e.g., keep the existing return True in the try and add an
explicit return False in an except block or after the try/finally as
appropriate).

In @tools/permission-auditor/tests/test_fix_commands.py:
- Around line 52-59: The test assumes apply_single_fix returns 'DRY_RUN' but
apply_single_fix (in auditor.py) can return 'DRY_RUN_NEEDS_SUDO' when running as
non-root; update the assertion in test_fix_commands.py (the block that calls
apply_single_fix with dry_run=True) to accept either 'DRY_RUN' or
'DRY_RUN_NEEDS_SUDO' (e.g., check that result['status'] is in a set { 'DRY_RUN',
'DRY_RUN_NEEDS_SUDO' }) so the test passes in both root and non-root
environments while leaving the rest of the command/permission assertions
unchanged.

tools/permission-auditor/scripts/demo.sh-13-13 (1)

13-13: cd without error handling can cause script to run in wrong directory.

tools/permission-auditor/src/auditor.py-679-680 (1)

679-680: Bare except clause hides errors and catches unintended exceptions.

This pattern appears multiple times in the file (lines 391, 679, 705). Bare except: catches everything including KeyboardInterrupt, SystemExit, and programming errors.

🔎 Proposed fix
-            except:
-                pass
+            except (OSError, IOError):

tools/permission-auditor/tests/test_fix_commands.py-52-59 (1)

52-59: Status assertion may need to include DRY_RUN_NEEDS_SUDO.

Based on the apply_single_fix API in auditor.py, when running as non-root and sudo is required, the status is DRY_RUN_NEEDS_SUDO, not DRY_RUN. The current assertion on line 55 only checks for DRY_RUN, which could cause test failures in non-root environments.

🔎 Proposed fix
-        assert result['status'] == 'DRY_RUN', f"Expected DRY_RUN, got {result['status']}"
+        assert result['status'] in ['DRY_RUN', 'DRY_RUN_NEEDS_SUDO'], \
+            f"Expected DRY_RUN or DRY_RUN_NEEDS_SUDO, got {result['status']}"
tools/permission-auditor/scripts/docker-entrypoint.sh-6-13 (1)

6-13: Quote variables and validate inputs for robustness.

The unquoted $HOST_UID and $HOST_GID variables could cause issues if they contain unexpected characters. Additionally, validating that these are numeric values would prevent command injection risks.

🔎 Proposed fix

🧹 Nitpick comments (16)
tools/permission-auditor/tests/test-docker.sh (1)

13-20: Quote command substitutions to prevent word splitting.

The unquoted $(id -u) and $(id -g) command substitutions could cause issues if the output contains spaces or special characters (though unlikely for UID/GID).

🔎 Proposed fix
 docker run --rm \
-  -e HOST_UID=$(id -u) \
-  -e HOST_GID=$(id -g) \
+  -e HOST_UID="$(id -u)" \
+  -e HOST_GID="$(id -g)" \

55-72: Consider capturing exit status from all tests.

Currently, only BASIC_TEST_RESULT affects the final exit code. Earlier test failures (Tests 1-4) are reported but don't influence the script's exit status, which could cause CI/CD pipelines to miss failures.

7-23: Hardcoded version strings make tests fragile.

The version '1.0.0' is hardcoded in multiple test functions. If the version changes in auditor.py, these tests will fail silently or require manual updates.

Consider importing the version constant from the auditor module:

from auditor import VERSION
# Then use VERSION in assertions

-def test_version_flag():
+def test_version_flag() -> bool:

🔇 Additional comments (23)
tools/permission-auditor/tests/__init__.py (1)

1-1: LGTM!

Empty __init__.py files are the correct, idiomatic way to establish a Python package in modern versions. This properly structures the tests directory as a package, enabling imports for the test modules.

tools/permission-auditor/test_permissions/check_perms.py (1)

5-23: LGTM - Diagnostic logic is clear and correct.

The diagnostic output format is well-structured and provides all necessary permission details for testing purposes.

tools/permission-auditor/tests/test-docker.sh (2)

1-12: LGTM - Test structure is clear.

The numbered test sections with descriptive echo statements provide good visibility into test progress.


21-36: Good test coverage with proper cleanup.

The test suite covers interactive mode, JSON output, and actual fixing operations. The cleanup step with docker stop ensures no lingering containers.

tools/permission-auditor/scripts/quick-test.sh (3)

1-22: LGTM - Test structure is sound.

The shellcheck warning (SC2319) at line 18 is a false positive. The $? variable is checked immediately in the conditional, so there's no risk of it being overwritten before use. The logic correctly accepts exit codes 0 or 1 for the basic scan.


24-38: Effective 777 permission detection test.

Good use of $$ for unique temp file names and helpful diagnostic output on failure.


40-53: LGTM - World-writable detection is properly tested.

The test correctly sets 666 permissions and checks for appropriate severity indicators. Cleanup is comprehensive.

tools/permission-auditor/tests/integration_test.py (1)

1-8: LGTM - Module setup is clean.

Module docstring and imports are appropriate for integration testing.

tools/permission-auditor/config/default.json (2)

1-28: Configuration structure looks solid.

The severity mappings, safe permissions, and exclude patterns are well-defined and appropriate for a permission auditing tool.


8-8: These configuration keys are not used in the code and do not cause any inconsistency.

The check_docker and docker.scan_containers settings in the configuration file are unused. Docker container scanning is controlled exclusively by the --docker command-line argument, not by configuration settings. The config keys appear to be legacy or planned functionality that was never implemented. No action needed.

Likely an incorrect or invalid review comment.

tools/permission-auditor/tests/test_basic.py (4)

1-10: Module setup looks good, but consider a minor improvement.

The sys.path manipulation is acceptable for test discovery. However, importing shutil at the module level (it's currently imported inside test_directory_scan) would be cleaner.


26-49: Test correctly validates 777 detection with proper cleanup.

Good use of finally block for cleanup. Consider adding type hint for consistency.


51-74: World-writable detection test is well-structured.

Proper isolation with temp files and cleanup. Same minor note about type hints applies.


105-121: Test runner implementation is correct.

Exit codes are properly set based on test results. This approach is straightforward and effective.

tools/permission-auditor/tests/test_fix_commands.py (4)

12-22: Good defensive fallback chain for username retrieval.

The multiple fallback methods handle various edge cases (containers, CI environments). Missing type hint and return type.


74-141: Test cases cover good variety of file types.

The test matrix covers scripts, configs, logs, regular files, and directories. This provides solid coverage for the permission suggestion logic.


188-227: Special files test validates system file handling.

Testing against /etc/shadow, /etc/sudoers, and /etc/passwd with mock findings is appropriate for unit testing the suggestion logic without requiring actual system file access.


229-245: Test runner follows consistent pattern with other test files.

Exit code handling is correct.

tools/permission-auditor/tests/test_full_features.py (2)

1-28: Comprehensive import set for full feature testing.

All necessary functions are imported from the auditor module. The import of Colors for formatting is a nice touch for readable test output.


613-693: Well-structured main function with proper error handling.

Good use of structured test result collection, summary output, and appropriate exit codes. The KeyboardInterrupt handling is a nice touch.

tools/permission-auditor/scripts/docker-entrypoint.sh (1)

15-15: Correct use of exec for entrypoint.

Using exec "$@" properly replaces the shell with the command, ensuring signal handling works correctly in Docker.

tools/permission-auditor/README.md (1)

1-18: Documentation is clear and well-structured.

The problem statement effectively explains the motivation. The features list covers all bounty requirements. Good use of emoji for visual clarity.

tools/permission-auditor/examples/advanced.Dockerfile (1)

51-67: Demo permission artifacts are well-documented.

Good demonstration of various permission scenarios for testing the auditor. The comments make the intent clear.

⚠️ Potential issue | 🔴 Critical

Remove the setuid binary example - this creates a real privilege escalation vulnerability.

Even for demonstration purposes, compiling and installing a setuid-root binary that spawns a shell is dangerous. If this image is accidentally deployed or the binary is extracted, it provides a trivial privilege escalation path. Use a mock/dummy binary or document the risk pattern without creating an actual exploit.

🔎 Proposed fix - use a safe alternative
-# Create a setuid binary for testing (real security issue)

-    gcc /app/test_suid.c -o /app/scripts/suid_test && \
-    chmod 4755 /app/scripts/suid_test 2>/dev/null || true && \

+    chmod 4755 /app/scripts/suid_test 2>/dev/null || true && \
+    rm /app/test_suid.c

Or better yet, skip creating a real binary entirely and just touch a file with setuid permissions for detection testing:

-# Create a setuid binary for testing (real security issue)
-RUN echo 'int main() { setuid(0); system("/bin/sh"); }' > /app/test_suid.c && \

The Dockerfile creates a real setuid-root binary (/app/scripts/suid_test) by
compiling /app/test_suid.c and setting chmod 4755, which is a real privilege
escalation risk; replace this with a safe test artifact: do not compile or
install a binary that spawns a shell—either create a non-executable placeholder
file or a harmless dummy executable (e.g., touch /app/scripts/suid_test and set
benign content) or simply touch a file and set the mode to mimic detection
(chmod 4755 on a non-functional placeholder) so the permission-auditor can
detect the pattern without introducing an exploitable program.

load_config function references undefined symbols and is never called.

  3. This function is defined but never used in main() or elsewhere

This will cause a NameError if the function is ever called. Either:

Test lacks setup, assertions, and proper structure.

This test script has several issues:

  1. Fragile path: sys.path.insert(0, '../src') depends on the current working directory being the test_permissions folder
  2. Missing test files: The test assumes dangerous_file.txt, world_writable.txt, and dangerous_dir exist but doesn't create them
  3. No assertions: Just prints results without validating correctness
  4. No exit code: Cannot determine pass/fail programmatically

Fix all issues with AI Agents 🤖
In @tools/permission-auditor/examples/advanced.Dockerfile.backup:
- Around line 69-73: The Dockerfile RUN that creates a setuid test binary (the
echo -> /app/test_suid.c, gcc /app/test_suid.c -o /app/scripts/suid_test, chmod
4755 ...) will fail because gcc isn't installed in the python:3.10-slim image;
fix by either adding a build tool install (e.g., install gcc or build-essential
in the existing apt-get block) so the gcc invocation succeeds, or make the
setuid build optional/guarded (skip the gcc/compile steps when gcc is absent or
move compilation to a separate build stage/multi-stage image) and ensure the
chmod step only runs if the binary was produced.
- Around line 82-84: The COPY+chmod step fails because chmod is executed after
USER appuser; move the RUN chmod +x /usr/local/bin/docker-entrypoint.sh so it
runs as root (i.e., place it immediately after the COPY and before the USER
appuser instruction) or temporarily switch to root around the chmod and then
switch back to appuser; also reorder Dockerfile instructions to put ENTRYPOINT
before CMD (ensure ENTRYPOINT ["docker-entrypoint.sh"] appears prior to any CMD)
so the entrypoint is defined in the conventional order.
- Around line 32-35: The final image currently copies Python packages to
/root/.local (COPY --from=builder /root/.local /root/.local) and sets ENV PATH
and ENV PYTHONPATH but the container runs as appuser (appuser) and cannot access
/root; change the artifact location to a user-accessible path (e.g., copy
builder /root/.local into /home/appuser/.local or install into
/home/appuser/.local during build) and update ENV PATH and ENV PYTHONPATH to
reference /home/appuser/.local so appuser can import packages, or alternatively
chown the copied /root/.local to appuser and ensure directory permissions allow
access before switching to appuser.

In @tools/permission-auditor/src/auditor.py:
- Line 456: The condition checking "others can read" is corrupted and causes a
syntax error; replace the malformed token
`0ostat_info.st_modestat_info.st_modestat_info.st_mode004` with the correct
octal mask `0o004` so the line reads `if permissions & 0o004:` (keep the
existing `permissions` variable and the comment intact).
- Around line 833-834: The subprocess.run invocation currently builds a shell
command string into cmd and uses shell=True (the lines setting cmd and calling
subprocess.run), which is unsafe; change it to call subprocess.run with a list
of arguments instead of a shell string (e.g., ["docker", "inspect",
container_name, "--format={{.Config.User}}"]) so quoting is handled by the
argument list, keep capture_output=True and text=True, and remove shell=True;
update any handling of cmd to use the new args list and preserve error checking
on the subprocess.run result.
- Around line 808-809: The call building cmd with container_name and using
subprocess.run(..., shell=True) is unsafe; change to invoking docker directly
without a shell by calling subprocess.run with a list of args (e.g.,
["docker","exec", container_name, "getent","passwd", str(host_uid)]) and remove
shell=True, redirect stderr via stderr=subprocess.DEVNULL instead of
"2>/dev/null", and implement the "not found" fallback by checking
result.returncode and/or result.stdout rather than relying on shell OR logic;
update the use site (the variables cmd, subprocess.run, container_name,
host_uid, and any surrounding UID mapping function) accordingly.

The script properly validates numeric input before attempting modifications and uses appropriate error suppression for non-critical operations that may fail in constrained container environments.

⚠️ Potential issue | 🔴 Critical

Python packages inaccessible to non-root user.

Packages are installed to /root/.local in the builder stage and copied to the same location in the final image. However, the container runs as appuser (line 76), who cannot access /root/.local due to restrictive permissions on /root. This will cause ModuleNotFoundError at runtime.

🔎 Proposed fix: install packages to a user-accessible location

⚠️ Potential issue | 🔴 Critical

Build will fail: gcc is not installed.

The python:3.10-slim image does not include gcc, and it's not installed in the apt-get block (lines 20-23). Since && chaining is used, the gcc failure will cause the entire RUN instruction to fail, breaking the Docker build.

🔎 Proposed fix: install build-essential or handle gcc absence

Option 1: Install gcc (adds image size)

 RUN apt-get update && \
     apt-get install -y --no-install-recommends \
     sudo \
+    gcc \
+    libc6-dev \
     && rm -rf /var/lib/apt/lists/*

Option 2: Make the entire setuid block optional

 # Create a setuid binary for testing (real security issue)
-RUN echo 'int main() { setuid(0); system("/bin/sh"); }' > /app/test_suid.c && \
-    gcc /app/test_suid.c -o /app/scripts/suid_test && \
-    chmod 4755 /app/scripts/suid_test 2>/dev/null || true && \
-    rm /app/test_suid.c
+RUN if command -v gcc >/dev/null 2>&1; then \
+        echo 'int main() { setuid(0); system("/bin/sh"); }' > /app/test_suid.c && \
+        gcc /app/test_suid.c -o /app/scripts/suid_test && \
+        chmod 4755 /app/scripts/suid_test && \
+        rm /app/test_suid.c; \

69-73, The Dockerfile RUN that creates a setuid test binary (the echo ->
/app/test_suid.c, gcc /app/test_suid.c -o /app/scripts/suid_test, chmod 4755
...) will fail because gcc isn't installed in the python:3.10-slim image; fix by
either adding a build tool install (e.g., install gcc or build-essential in the
existing apt-get block) so the gcc invocation succeeds, or make the setuid build
optional/guarded (skip the gcc/compile steps when gcc is absent or move
compilation to a separate build stage/multi-stage image) and ensure the chmod
step only runs if the binary was produced.

Build fails: RUN chmod executes as non-root user without write permissions.

After USER appuser (line 76), the RUN chmod +x on line 83 executes as appuser. However, /usr/local/bin/ is owned by root with mode 755, so appuser cannot modify files there. This will fail with "Permission denied".

Additionally, ENTRYPOINT is defined after CMD, which is unconventional (ENTRYPOINT typically precedes CMD).

🔎 Proposed fix: reorder instructions to run chmod before USER switch
+# Add entrypoint script for UID/GID mapping
+COPY --chown=appuser:appgroup docker-entrypoint.sh /usr/local/bin/
+RUN chmod +x /usr/local/bin/docker-entrypoint.sh
+ENTRYPOINT ["docker-entrypoint.sh"]

 # Switch to non-root user
 USER appuser
 
 # Default to safe dry-run mode (REQUIREMENT: "Fixes with single command (safely)")

82-84, The COPY+chmod step fails because chmod is executed after USER appuser;
move the RUN chmod +x /usr/local/bin/docker-entrypoint.sh so it runs as root
(i.e., place it immediately after the COPY and before the USER appuser
instruction) or temporarily switch to root around the chmod and then switch back
to appuser; also reorder Dockerfile instructions to put ENTRYPOINT before CMD
(ensure ENTRYPOINT ["docker-entrypoint.sh"] appears prior to any CMD) so the
entrypoint is defined in the conventional order.

45-47: Fix comment indentation.

Same indentation issue as in test_777_file - these security comments should be indented inside the try block.

🔎 Proposed fix
     try:
-    # SECURITY TEST: Intentionally setting dangerous permissions for testing
-    # This file is in temp directory and will be deleted immediately
-    # NOSONAR - This is a security test for the permission auditor
+        # SECURITY TEST: Intentionally setting dangerous permissions for testing
+        # This file is in temp directory and will be deleted immediately
+        # NOSONAR - This is a security test for the permission auditor
         os.chmod(temp_path, 0o666)

50-56: Consider checking subprocess return code.

Same as test_777_file - consider validating the subprocess return code to ensure the auditor completed successfully.

🔎 Proposed enhancement
         result = subprocess.run(
             ['python3', 'src/auditor.py', temp_path, '--fix'],
             capture_output=True,
             text=True
         )
         
+        assert result.returncode == 0, f"Auditor failed with return code {result.returncode}"
         assert "HIGH" in result.stdout or "WORLD_WRITABLE" in result.stdout

8-8: Add type hints and remove unreachable code.

As previously noted, this function is missing a return type hint (required per coding guidelines) and lines 35-36 contain unreachable dead code that will never execute after the finally block.

Based on coding guidelines: "Type hints required in Python code"

Also applies to: 35-36


38-38: Add type hints and remove unreachable code.

As previously noted for test_777_file, this function also lacks a return type hint and has unreachable dead code at lines 63-64 after the finally block.

Based on coding guidelines: "Type hints required in Python code"

Also applies to: 63-64

6-6: Remove unused import.

The stat module is imported but never used in this file.

🔎 Proposed fix
 import os
 import tempfile
 import subprocess
-import stat

15-17: Fix comment indentation.

The security comments are indented at the same level as the try statement, but they logically belong inside the try block and should be indented accordingly.

🔎 Proposed fix
     try:
-    # SECURITY TEST: Intentionally setting dangerous permissions for testing
-    # This file is in temp directory and will be deleted immediately
-    # NOSONAR - This is a security test for the permission auditor
+        # SECURITY TEST: Intentionally setting dangerous permissions for testing
+        # This file is in temp directory and will be deleted immediately
+        # NOSONAR - This is a security test for the permission auditor
         os.chmod(temp_path, 0o777)

21-28: Consider checking subprocess return code.

The test validates stdout content but doesn't verify whether the subprocess completed successfully. Consider checking result.returncode to ensure the auditor ran without errors.

🔎 Proposed enhancement
         result = subprocess.run(
             ['python3', 'src/auditor.py', temp_path, '--fix'],
             capture_output=True,
             text=True
         )
         
+        assert result.returncode == 0, f"Auditor failed with return code {result.returncode}"
         assert "CRITICAL" in result.stdout
         assert "777" in result.stdout
