CVE-2026-32317

Estado: AnalizadaMedia (5.9)—

Cryptomator for Android offers multi-platform transparent client-side encryption for files in the cloud. Prior to version 1.12.3, an integrity check vulnerability allows an attacker tamper with the vault configuration file leading to a man-in-the-middle vulnerability in Hub key loading mechanism. Before this fix, the client trusted endpoints from the vault config without host authenticity checks, which could allow token exfiltration by mixing a legitimate auth endpoint with a malicious API endpoint. Impacted are users unlocking Hub-backed vaults with affected client versions in environments where an attacker can alter the vault.cryptomator file. This issue has been patched in version 1.12.3.

Antes de esta corrección, el cliente confiaba en los puntos finales de la configuración de la bóveda sin comprobaciones de autenticidad del host, lo que podría permitir la exfiltración de tokens al mezclar un punto final de autenticación legítimo con un punto final de API malicioso. Los usuarios afectados son aquellos que desbloquean bóvedas respaldadas por Hub con versiones de cliente afectadas en entornos donde un atacante puede alterar el archivo vault.cryptomator. Este problema ha sido parcheado en la versión 1.12.3."
