CVE-2026-42208

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. From version 1.81.16 to before version 1.83.7, a database query used during proxy API key checks mixed the caller-supplied key value into the query text instead of passing it as a separate parameter. An unauthenticated attacker could send a specially crafted Authorization header to any LLM API route (for example POST /chat/completions) and reach this query through the proxy's error-handling path. An attacker could read data from the proxy's database and may be able to modify it, leading to unauthorised access to the proxy and the credentials it manages. This issue has been patched in version 1.83.7.

      "value": "LiteLLM es un servidor proxy (AI Gateway) para llamar a las API de LLM en formato OpenAI (o nativo). Desde la versión 1.81.16 hasta antes de la versión 1.83.7, una consulta de base de datos utilizada durante las comprobaciones de claves de API del proxy mezclaba el valor de la clave proporcionado por el llamador en el texto de la consulta en lugar de pasarlo como un parámetro separado. Un atacante no autenticado podría enviar un encabezado de autorización especialmente diseñado a cualquier ruta de API de LLM (por ejemplo, POST /chat/completions) y alcanzar esta consulta a través de la ruta de manejo de errores del proxy. Un atacante podría leer datos de la base de datos del proxy y podría modificarlos, lo que llevaría a un acceso no autorizado al proxy y a las credenciales que gestiona. Este problema ha sido parcheado en la versión 1.83.7."
