Attackers can present a token with an unverified email address matching a victim's account to inherit the victim's role, including proxy_admin privileges, and permanently overwrite the victim's stored identity binding to retain persistent unauthorized access to administrative endpoints exposing API keys and user management.","cvssScore":8.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","cwes":["CWE-1390"],"vendors":[],"products":[],"references":[{"url":"https://www.ox.security/blog/litellm-an-ordinary-login-token-can-become-someone-elses-admin-account/","tags":[]},{"url":"https://www.vulncheck.com/advisories/litellm-weak-jwt-authentication-via-email-based-user-lookup","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
