If you cannot patch yet, restrict access to the /user/update endpoint to trusted users only and monitor for unauthorized privilege escalations. Follow updates from the vendor and Red Hat advisory for official remediation steps.
Description
LiteLLM prior to 1.83.10 allows a user to modify their own user_role via the /user/update endpoint. While the endpoint correctly restricts users to updating only their own account, it does not restrict which fields may be changed. A user who can reach this endpoint can set their role to proxy_admin, gaining full administrative access to LiteLLM including all users, teams, keys, models, and prompt history. Users with the org_admin role have legitimate access to this endpoint and can exploit this vulnerability without chaining any additional flaw.
