LiteLLM is a proxy server (AI Gateway) to call LLM APIs in OpenAI (or native) format. Prior to 1.83.10-stable, LiteLLM's /health/test_connection endpoint resolved request-supplied environment and OIDC file references in litellm_params, allowing a proxy administrator or another privileged caller with permission to test model connections to read files from the local filesystem via an oidc/file/ reference. This issue is fixed in version 1.83.10-stable.

  • WID-SEC-W-2026-2263LiteLLM: Mehrere SchwachstellenDeutsch2026-07-08csaf · cert_bundDE

    Ein Angreifer kann mehrere Schwachstellen in LiteLLM ausnutzen, um Informationen offenzulegen, Daten zu manipulieren, Code auszuführen und um Sicherheitsmaßnahmen zu umgehen.

  • GHSA-4g5m-c9r5-49xfLiteLLM: Local file read via request-supplied OIDC file references2026-07-22ghsa · osvUS

    ### Impact LiteLLM's `/health/test_connection` endpoint resolved request-supplied environment and OIDC file references in `litellm_params`. A proxy administrator, or another privileged caller with permission to test model connections, could cause LiteLLM to read files from the local filesystem via an `oidc/file/` reference. Because exploitation requires privileged proxy access, this is treated as a defense-in-depth issue rather than a cross-tenant privilege bypass. ### Patches The issue is fixed in `1.83.10-stable`. LiteLLM recommend upgrading to `1.83.10-stable` or later. ### Workarounds Restrict `/health/test_connection` access to trusted administrators only.
