Summary
LiteLLM: Local file read via request-supplied OIDC file references
Details

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.

Severity
