Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
MLflow versions 3.13.0 through 3.15.2 accept an unvalidated api_base when creating an AI Gateway secret, so the stored address can point at internal hosts. Any authenticated user, including read-only accounts, can create such a secret and use the gateway proxy endpoint to make requests to it and read the full response, which may expose cloud instance credentials through metadata services. No fixed version is listed.
