CVE-2026-47102
HighCVSS 8.8Exploitation Probability (EPSS)
Low risk47th percentile - higher than 47% of all known CVEs
Summary
LiteLLM prior to version 1.83.10 allows a user to modify their own user_role via the /user/update endpoint. The endpoint restricts updates to the user's own account but does not validate which fields can be changed, enabling a user to escalate their role to proxy_admin.
Risk Assessment
The risk is that a regular user can gain full administrative access to LiteLLM, potentially compromising all users, teams, keys, models, and prompt history.
Recommendation
Immediately upgrade LiteLLM to version 1.83.10 or later, which fixes this vulnerability. Additionally, restrict access to the /user/update endpoint to trusted users only.
Original NVD description (English source)
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.
