fix(security): tighten command injection regex + add ignore rules logging#328
Merged
Conversation
…ging - Tighten injection/exec regex: only flag subprocess.run when dynamic input signals present (f-string, format(), shell=True, string concat with user input). Literal list calls like subprocess.run(cmd) are safe. - Add debug logging to apply_ignore_rules for better diagnostics - Add unit tests for ignore_rules (title match, issue_type match, empty, case insensitive) - Add unit tests for security_scanner (no FP on literal list, triggers on f-string and shell=True) Fixes #326

Problem
The injection/exec security scanner regex matches every subprocess.run() call,
including safe ones with controlled literal lists. This causes false positives
in legitimate subprocess calls.
Also, apply_ignore_rules() had no debug logging, making it impossible to
diagnose filtering issues.
Changes
(f-string, format(), shell=True, string concat with user input)
Closes #326
