CVE-2025-61779

Confidential Containers's Trustee project contains tools and components for attesting confidential guests and providing secrets to them. In versions prior to 0.15.0, the attestation-policy endpoint didn't check if the kbs-client submitting the request was actually authenticated (had the right key). This allowed any kbs-client to actually change the attestation policy. Version 0.15.0 fixes the issue.

Summary		(es) El proyecto Trustee de Confidential Containers contiene herramientas y componentes para atestiguar invitados confidenciales y proporcionarles secretos. En versiones anteriores a la 0.15.0, el endpoint de política de atestación no verificaba si el kbs-cliente que enviaba la solicitud estaba realmente autenticado (tenía la clave correcta). Esto permitía a cualquier kbs-cliente cambiar realmente la política de atestación. La versión 0.15.0 corrige el problema.
