CVE-2026-47102

LiteLLM < 1.83.10 Privilege Escalation via User Update

Published May 21, 2026 CVSS 4.0 · 8.7 High EPSS < 1% KEV · Not listed
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.
