📄 Description
The indexed data-plane routes (/api/chat, /api/generate, /api/embed, /api/embeddings and the /v1/* proxies) trusted a user-supplied url_idx path parameter and skipped the model-to-backend allow-list, letting a verified user route a request to an admin-disabled backend and have its configured API key attached. Validate the supplied index against the model's enabled backend list before use; admins and bypass mode are unaffected.
