From 0db1427e5631e9d104fef5e8e597169034dea975 Mon Sep 17 00:00:00 2001 From: altynai9128 Date: Mon, 5 Jan 2026 14:38:59 +0300 Subject: [PATCH 1/4] feat: add permission auditor tool Complete implementation for bounty #446: - Scans for dangerous permissions (777, world-writable) - Explains security risks in plain English - Suggests context-aware permission fixes - Safe operation with dry-run mode by default - Docker/container UID mapping support The tool is placed in tools/permission-auditor/ for easy testing. All source code, tests, and documentation included.
