Summary By MatterAI

🔄 What Changed

Implemented filename sanitization using path.basename across all PlanMemoryManager operations (writeFile, readFile, hasFile, deleteFile). Added entry.isFile() validation during directory scanning and improved error logging for file deletions.

🔍 Impact of the Change

Hardens the Planning Mode storage logic against directory traversal and ensures memory is only populated with valid file entries, increasing system reliability and security.

Storage Hardening src/core/kilocode/PlanMemoryManager.ts	Added path.basename sanitization and isFile checks.

🧪 Test Added/Recommended

Recommended

• Unit Tests: Verify PlanMemoryManager correctly handles malicious path strings (e.g., ../, /etc/) by ensuring they are stripped to the basename.

🔒 Security Vulnerabilities

N/A

Context

Ensuring that the virtual planning memory is strictly confined to its designated directory and only processes valid file types.

Implementation

Wrapped all incoming filename parameters in path.basename() to prevent directory traversal. Updated the readdir loop to filter for files using entry.isFile() and added a check to prevent redundant memory writes if a file is already loaded.

How to Test

1. Invoke writeFile with a path containing traversal characters (e.g., test/../../secret.txt).
2. Verify the file is stored as secret.txt within the plan-memory directory.
3. Check logs for a warning if deleteFile is called on a non-existent file.

🧪 PR Review is completed: Review of Plan Mode implementation. Identified critical security issues regarding path traversal in file operations and a race condition in memory initialization.

[matter-code-review]

✅ Reviewed the changes: The changes successfully address the previous security and logic concerns. The use of path.basename mitigates path traversal risks, and the race condition in loadExistingFiles is handled correctly by checking for existence after the async read.
