Should I care?
This matters if:
- Apps serving files or reading paths from user input
- File upload endpoints
Not relevant if:
- No file operations use user-supplied paths
- All paths are resolved against a fixed root
How it breaks apps
1
User input used in file path
2
Path traversal escapes root
3
Attacker reads arbitrary files
4
Sensitive data exposure

Technical details
Risk by Environment
Production (public-facing)
HIGH
Patch soon. Exploitation requires specific conditions but impact is severe.
Staging
MEDIUM
Schedule patch. Review if this environment is network-accessible.
Internal services
MEDIUM
Assess exposure. Patch if the service handles sensitive data.
Local dev only
LOW
Minimal risk in isolated dev environments.
AI Development Risk
This vulnerability pattern is commonly introduced when AI generates code.
CWE-22
Path traversal
LLMs tend to construct file paths from user input without proper canonicalization or sandboxing.
