REDHAT-BUG-2455474: High severity LiteLLM LiteLLM vulnerability

LiteLLM is a proxy server (AI Gateway) to call LLM APIs in OpenAI (or native) format. Prior to 1.83.0, he /config/update endpoint does not enforce admin role authorization. A user who is already authenticated into the platform can then use this endpoint to modify proxy configuration and environment variables, register custom pass-through endpoint handlers pointing to attacker-controlled Python code, achieving remote code execution, read arbitrary server files by setting UILOGOPATH and fetching via /getimage, and take over other privileged accounts by overwriting UIUSERNAME and UIPASSWORD environment variables. Fixed in v1.83.0.
