Enhanced Bash Security Checks

What: Improved detection of backtick command substitution with escape-aware parsing

Details:

  • Backtick checks now execute before other pattern matching
  • More accurate detection prevents false positives from escaped backticks
  • Evidence: CV6() at line 205030, RV6() at line 205296
