Security Findings5

Severity	Finding	Layer	Location
CRITICAL	Arbitrary command execution Python shell execution (os.system, subprocess) Review all shell execution calls. Ensure commands are static (not built from user input), use absolute paths, and are strictly necessary. Prefer library APIs over shell commands.	Manifest	skills/vulnerability-scanner/scripts/security_scan.py:134
CRITICAL	Arbitrary command execution Python dynamic code execution (exec/eval/compile) Review all shell execution calls. Ensure commands are static (not built from user input), use absolute paths, and are strictly necessary. Prefer library APIs over shell commands.

CRITICAL	Arbitrary command execution Python dynamic code execution (exec/eval/compile) Review all shell execution calls. Ensure commands are static (not built from user input), use absolute paths, and are strictly necessary. Prefer library APIs over shell commands.	Manifest	skills/vulnerability-scanner/scripts/security_scan.py:64
CRITICAL	File read + network send exfiltration .env file access Remove access to sensitive files not required by the skill's stated purpose. SSH keys, cloud credentials, and browser data should never be read by skills unless explicitly part of their declared functionality.	Manifest	skills/vulnerability-scanner/scripts/security_scan.py:90
HIGH	Dangerous call: subprocess.run() Call to 'subprocess.run()' detected in function 'scan_dependencies'. This can execute arbitrary code. Avoid using dangerous functions like exec/eval/os.system. Use safer alternatives.	Static	skills/vulnerability-scanner/scripts/security_scan.py:134
