CVE-2026-12772Public exploitNetwork attack vector

Authenticated session disruption via expiration mishandling

Published Jun 21, 2026 · Updated Jun 21, 2026

Insufficient session expiration in LiteLLM 1.82.0 through 1.82.2 allows remote authenticated users to disrupt sessions remotely. The authenticate_user function in litellm/proxy/auth/login_utils.py mishandles session expiration during database-backed PROXY_ADMIN API-key generation; the public record does not disclose the manipulated input or exact state transition. A valid low-privilege session is required, and the documented consequence is limited to session expiration rather than broader access or code execution.
