🛡️ Sentinel: [CRITICAL] Fix command injection in file opening

[haseeb-heaven]

🚨 Severity: CRITICAL
💡 Vulnerability: Command injection vulnerability on Windows when opening resource files due to subprocess.call with shell=True.
🎯 Impact: An attacker could execute arbitrary commands by creating a file with a maliciously crafted name (e.g., containing & or ^) and tricking the application into opening it.
🔧 Fix: Replaced subprocess.call(['start', filename], shell=True) with os.startfile(filename).
✅ Verification: Run flake8 and python3 -m pytest tests/.

📝 Walkthrough

Walkthrough

In UtilityManager._open_resource_file, the Windows branch is changed from subprocess.call(['start', filename], shell=True) to os.startfile(filename), eliminating shell injection risk. A new .jules/sentinel.md entry documents the vulnerability and the applied fix.

Changes

Windows File-Open Security Fix

Layer / File(s)	Summary
Replace subprocess shell=True with os.startfile libs/utility_manager.py, .jules/sentinel.md	_open_resource_file on Windows now uses os.startfile(filename) instead of subprocess.call(['start', filename], shell=True); the sentinel doc records the unsafe pattern and its remediation.

Poem

🐇 A shell with True let bad args sneak in,
One tiny swap and safety could win.
os.startfile hops right to the task,
No injection to dodge, no shell to unmask.
The rabbit says: secure by design! 🎉
