CVE-2025-66405

Portkey.ai Gateway is a blazing fast AI Gateway with integrated guardrails. Prior to 1.14.0, the gateway determined the destination baseURL by prioritizing the value in the x-portkey-custom-host request header. The proxy route then appends the client-specified path to perform an external fetch. This can be maliciously used by users for SSRF attacks. This vulnerability is fixed in 1.14.0.

Summary		(es) Portkey.ai Gateway es un Gateway de IA extremadamente rápido con barreras de seguridad integradas. Versiones anteriores a 1.14.0, el gateway determinaba la baseURL de destino priorizando el valor en el encabezado de solicitud x-portkey-custom-host. La ruta del proxy luego añade la ruta especificada por el cliente para realizar una recuperación externa. Esto puede ser utilizado maliciosamente por los usuarios para ataques SSRF. Esta vulnerabilidad está corregida en 1.14.0.
