Security Review Summary
This PR introduces a JavaScript file containing multiple critical security vulnerabilities that must be addressed before merging:
Critical Issues Found:
- 8 OS Command Injection vulnerabilities (CWE-78) - User-controlled data from database and file uploads is directly interpolated into shell commands without sanitization
- 1 Path Traversal vulnerability (CWE-22) - File upload functionality allows writing files outside intended directory
Impact:
These vulnerabilities allow attackers to:
- Execute arbitrary system commands on the server
- Access or modify files outside the intended directory structure
- Potentially gain full system compromise
Required Actions:
All identified security vulnerabilities must be fixed using the provided code suggestions before this PR can be merged. The suggested fixes use JSON.stringify() for proper shell escaping and path.basename() to prevent path traversal attacks.
Status: ❌ REQUIRES CHANGES - Critical security vulnerabilities block merge.
You can now have the agent implement changes and create commits directly on your pull request's source branch. Simply comment with /q followed by your request in natural language to ask the agent to make changes.
