CVE-2026-107935

Estado: Pendiente de análisisCrítica (9.3)—

Se encontró una vulnerabilidad de traversal de directorios en gvproxy, el reenviador de red proporcionado por el paquete gvisor-tap-vsock. El extremo /services/forwarder/expose sin autenticación no valida la ruta del socket proporcionada por el autor de la llamada, permitiendo a un atacante eliminar archivos arbitrarios en el sistema host.
