      "value": "The /v1/upload/sbom endpoint extracts the iss claim from the attacker-supplied JWT with signature verification disabled, then interpolates that string into three log statements before any validation gate. Because the configured log format (\"%(asctime)s - %(name)s - %(levelname)s - %(message)s\") renders newlines literally, an unauthenticated attacker can forge log records that are byte-for-byte indistinguishable from PIA's genuine \"Successfully authenticated project\" message. PIA is an authentication broker whose logs are explicitly relied upon for incident response (DESIGN.md §5.4 lists \"Token verifications\" and \"Errors\" as events to log), so the ability to plant fake auth-success entries directly undermines the audit trail the service exists to produce."

      "lang": "es",
      "value": "El endpoint /v1/upload/sbom extrae la declaración ’iss’ del JWT proporcionado por el atacante con la verificación de firma deshabilitada, luego interpola esa cadena en tres sentencias de registro antes de cualquier puerta de validación. Debido a que el formato de registro configurado (’%(asctime)s - %(name)s - %(levelname)s - %(message)s’) renderiza los saltos de línea literalmente, un atacante no autenticado puede falsificar registros de log que son indistinguibles byte a byte del mensaje genuino de PIA ’Proyecto autenticado con éxito’. PIA es un bróker de autenticación cuyos registros se utilizan explícitamente para la respuesta a incidentes (DESIGN.md §5.4 enumera ’Verificaciones de token’ y ’Errores’ como eventos a registrar), por lo que la capacidad de insertar entradas falsas de éxito de autenticación socava directamente la pista de auditoría que el servicio existe para producir."
