Vulnerability from fkie_nvd - Published: 2026-02-23 06:16 - Updated: 2026-02-23 18:13
Severity ?
2.5 (Low) - CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N
Summary
A vulnerability was identified in AliasVault App up to 0.25.3 on Android/iOS. This vulnerability affects unknown code of the file shared_prefs/aliasvault.xml of the component Backup Handler. The manipulation of the argument accessToken/refreshToken/metadata/key_derivation_params/auth_methods leads to exposure of backup file to an unauthorized control sphere. An attack has to be approached locally. The attack is considered to have high complexity. It is stated that the exploitability is difficult. The exploit is publicly available and might be used. Upgrading to version 0.26.0 is able to resolve this issue. The identifier of the patch is 873ecc03f92238e162f98a068ad56069a922b4f6/0bd662320174d8265dfe3b05a04bc13efc960532. It is recommended to upgrade the affected component. The creator of the software explains: "Because of AliasVault's zero-knowledge encryption design, the tokens stored in aliasvault.xml are API session tokens that cannot decrypt the vault on their own: the master password is required for that. So while this isn't a direct vault compromise risk, there's no reason to include them in backups either."

      "value": "Se ha descubierto una vulnerabilidad en AliasVault App hasta la versi\u00f3n 0.25.3 en Android/iOS. Esta vulnerabilidad afecta a c\u00f3digo desconocido del archivo shared_prefs/aliasvault.xml del componente Gestor de Copias de Seguridad. Al manipular el argumento accessToken/refreshToken/metadata/key_derivation_params/auth_methods se logra exponer el archivo de copia de seguridad a una esfera de control no autorizada. El ataque debe realizarse en local. Se considera que el ataque tiene una complejidad alta. Se afirma que es dif\u00edcil de explotar. El exploit est\u00e1 disponible p\u00fablicamente y podr\u00eda ser utilizado. La actualizaci\u00f3n a la versi\u00f3n 0.26.0 puede resolver este problema. El identificador del parche es 873ecc03f92238e162f98a068ad56069a922b4f6/0bd662320174d8265dfe3b05a04bc13efc960532. Se recomienda actualizar el componente afectado. El creador del software explica: \u0027Debido al dise\u00f1o de cifrado de conocimiento cero de AliasVault, los tokens almacenados en aliasvault.xml son tokens de sesi\u00f3n de API que no pueden descifrar la b\u00f3veda por s\u00ed solos: se necesita la contrase\u00f1a maestra para ello. As\u00ed que, aunque esto no es un riesgo directo de compromiso de la b\u00f3veda, tampoco hay raz\u00f3n para incluirlos en las copias de seguridad.\u0027"
