CVE-2026-33314

Estado: AnalizadaMedia (6.5)—

pyLoad is a free and open-source download manager written in Python. Prior to version 0.5.0b3.dev97, a Host Header Spoofing vulnerability in the @local_check decorator allows unauthenticated external attackers to bypass local-only restrictions. This grants access to the Click'N'Load API endpoints, enabling attackers to remotely queue arbitrary downloads, leading to Server-Side Request Forgery (SSRF) and Denial of Service (DoS). This issue has been patched in version 0.5.0b3.dev97.

Antes de la versión 0.5.0b3.dev97, una vulnerabilidad de suplantación de encabezado de host en el decorador @local_check permite a atacantes externos no autenticados eludir las restricciones de solo acceso local. Esto otorga acceso a los puntos finales de la API de Click'N'Load, lo que permite a los atacantes poner en cola descargas arbitrarias de forma remota, lo que lleva a la falsificación de petición del lado del servidor (SSRF) y a la denegación de servicio (DoS).
