Unauthenticated file read via unnormalized path concatenation
Published Aug 27, 2026 · Updated Aug 27, 2026
Path traversal in Yu AI Code Mother 4.3 allows remote attackers to read files outside the preview root through the static resource API. The /api/static/{deployKey}/ handler concatenates a user-controlled path to the preview root without normalizing it or enforcing containment. No authentication is required, and crafted traversal sequences expose any file readable by the service account outside that root.
