From b6c0ec0e9b913cfcd46ab9c39c2b198be9e2ae5f Mon Sep 17 00:00:00 2001 From: cschantz Date: Fri, 9 Jan 2026 16:17:23 -0500 Subject: [PATCH] Fix security issues and QA false positives MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Security fixes in lib/mysql-analyzer.sh: - Added -- separator to grep/sed/awk/wc commands to prevent filename injection - Fixed 10 ESCAPE issues (lines 130, 153, 180, 208, 210, 320, 324, 405, 507, 513) QA script improvements in tools/toolkit-qa-check.sh: - Updated ESCAPE check (CHECK 66) to recognize -- as safe pattern - Updated HARDCODED-PATH check (CHECK 81) to skip control panel abstraction libraries - Now correctly excludes domain-discovery.sh, plesk-helpers.sh, user-manager.sh from hardcoded path warnings - Reduced false positives by ~23 issues 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- lib/mysql-analyzer.sh | 20 ++++++++++---------- tools/toolkit-qa-check.sh | 11 ++++++++--- 2 files changed, 18 insertions(+), 13 deletions(-) diff --git a/lib/mysql-analyzer.sh b/lib/mysql-analyzer.sh index 60fb4e6..ab110e5 100755 --- a/lib/mysql-analyzer.sh +++ b/lib/mysql-analyzer.sh @@ -127,7 +127,7 @@ map_database_to_user_domain() { # Return cached if exists if [ -f "$map_file" ];
