CVE-2026-12795Public exploitNetwork attack vector

Unauthenticated SSO data exposure via debug endpoints

Published Jun 21, 2026 · Updated Jun 21, 2026

Missing authentication in LiteLLM 1.82.0 through 1.82.2 allows remote attackers to obtain SSO debug data through exposed endpoints. The debug login and callback routes omit an authentication dependency and render identity-provider profile and OAuth response data in an HTML page. Exploitation requires a configured SSO provider and completion of its flow; Google or Microsoft configurations expose returned access and identity tokens.
