Description OSIDB Bzimport 2026-11-05 22:02:24 UTC 
Coder 2.28.0 before 2.29.22, 2.30.0 before 2.34.13, 2.35.0 before 2.35.10, 2.36.0 before 2.36.8, 2.37.0 before 2.37.5, and 2.38.0 before 2.38.1 contains a path traversal vulnerability in the AI Gateway passthrough router, which forwards percent-encoded dot segments upstream without rejecting them. Authenticated users can send paths such as %2e%2e or ..%2F under allowlisted prefixes to reach unintended provider endpoints using the deployment's centrally managed provider key.
