CVE-2026-59819
Full vulnerability record from the local CVENow database.
Description
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.

Antes de la versión 1.83.10-stable, el endpoint /health/test_connection de LiteLLM resolvía referencias de archivos OIDC y de entorno suministradas en la solicitud en litellm_params, permitiendo a un administrador de proxy o a otro llamador privilegiado con permiso para probar conexiones de modelos leer archivos del sistema de archivos local a través de una referencia oidc/file/. Este problema está solucionado en la versión 1.83.10-stable."
