Is this vulnerability remotely exploitable?

Yes, if the LiteLLM instance is exposed over the network and an attacker can obtain any valid user credentials, they can remotely call `/config/update` and potentially achieve code execution or privilege escalation.

What level of access does an attacker need?

The attacker must be an authenticated user of the LiteLLM platform, but does not need administrative privileges. Any account that can reach `/config/update` is sufficient under the vulnerable configuration.

What is the safest general fix pattern?

Apply strict role-based access control to all configuration and management endpoints, ensuring only designated administrative roles can change sensitive settings. Additionally, restrict which configuration fields are mutable at runtime and isolate administrative APIs from general user traffic.
