Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Multiple independent auth bypass fixes across OAuth routes, handlers, and permissions indicate a systemic weakness in authorization enforcement, with legacy tokens and endpoint mismatches being common root causes.
Path Traversal: Path traversal was fixed in both the API client and schema validation, showing a pattern of unsanitized user input flowing into URL construction across different layers.
Race Condition: Two distinct race fixes in OAuth token refresh locking highlight a fragile concurrency handling around token rotation, risking token corruption and auth failures.
