Doc Text:
A flaw was found in LiteLLM. A user with access to the `/user/update` endpoint can exploit a privilege escalation vulnerability. By modifying their own `user_role` to `proxy_admin`, an attacker can gain full administrative access to LiteLLM, including control over all users, teams, keys, models, and prompt history.

Description OSIDB Bzimport 2026-05-21 21:01:14 UTC 
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.
