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.","state":0,"publishedAt":"2026-09-28T19:26:01.155+00:00","modifiedAt":"2026-10-01T15:21:59.696+00:00","affected":[{"ecosystem":"Vendor product","name":"litellm","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unknown\",\n                    \"vendor\": \"BerriAI\",\n                    \"product\": \"litellm\",\n                    \"packageURL\": \"pkg:github/BerriAI/litellm\",\n                    \"repo\": \"https://github.com/BerriAI/litellm\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\",\n                            \"lessThanOrEqual\": \"1.102.1\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"git\",\n                            \"lessThanOrEqual\": \"f4308bc124eebc783dfc51790ce8db27ed21ae00\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":7.6,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","score":8.1,"severity":"HIGH"}],"references":["https://www.ox.security/blog/litellm-an-ordinary-login-token-can-become-someone-elses-admin-account/","https://www.vulncheck.com/advisories/litellm-weak-jwt-authentication-via-email-based-user-lookup"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-93355","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-93355","identifiers":["CVE-2026-93355"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
