📄 Description

GET /api/v1/models/model?id=<model_id> at routers/models.py:412 returned the full model.model_dump() to any caller with read access, including the params dict that holds the admin-curated system prompt and other behavior config. The user-facing /api/models endpoint already strips this via utils/models.py:170,210 with the comment "Remove params to avoid exposing sensitive info", and /api/v1/models/list gates by write permission so non-curators don't see the model in their workspace listing at all. The per-id endpoint missed the same gate, so a user with read-only access (e.g. granted access to use the model in chat) could open /workspace/models/edit?id= in the browser and read the system prompt verbatim from the network response, even though saving was correctly blocked.

Compute write_access once at the top of the handler so it can serve both the response-shape decision and the response field. When the caller lacks write access, replace params with an empty dict in the serialised response. Owners, admins under BYPASS_ADMIN_ACCESS_CONTROL, and explicit write-grant holders still get the full payload so the workspace edit UI keeps working for users who legitimately curate the model.

Read-permission users continue to receive everything else they need to chat with the model — the chat path resolves prompt/params server-side from the stored ModelModel and never echoes them back through this endpoint.
