**References**:
- ASVS V8.X.X: [requirement text]
- CWE-XXX: [vulnerability type]
| Severity | Criteria | Examples |
|---|---|---|
| Critical | Direct unauthorized access | Admin bypass, full IDOR, privilege escalation |
| High | Significant access control gap | Missing auth on sensitive endpoint, horizontal escalation |
| Medium | Limited unauthorized access | Partial data exposure, inconsistent enforcement |
| Low | Best practice gaps | Verbose errors revealing permissions, minor path issues |
