{"id":"CVE-2026-47102","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-47102","generatedAt":"2026-10-28T07:04:50.965Z","title":"LiteLLM prior to 1.83.10 allows a user to modify their own user_role via the /user/update endpoint.","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.","published":"2026-05-21T21:16:33.000Z","lastModified":"2026-10-08T16:17:17.000Z","status":"Modified","sourceIdentifier":"disclosure@vulncheck.com","cvss":{"version":"4.0","score":8.7,"severity":"HIGH","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-863","CWE-915"],"affected":["litellm/litellm"],"epss":{"score":0.00654,"percentile":0.51115,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.65%).
