coder vulnerability

Coder from 2.10.0 before 2.34.8 has an unauthenticated agent debug HTTP server on 127.0.0.1:2113 whose /debug/manifest handler returns the full agent manifest, including template-provided environment variable values. A lower-privileged Unix user or process in the same workspace can query this endpoint to read credentials such as cloud keys or registry tokens.
