CVE-2026-50007

Estado: AplazadaAlta (7.2)—

Actual is an open-source personal finance application. Prior to 26.7.0, a missing authorization issue allows a shared user with user_access on a budget file to perform owner-only file management actions. A non-owner shared user can call file-management endpoints intended for higher-privilege users, including /delete-user-file, /reset-user-file, and /user-create-key, because requireFileAccess treats ordinary shared access as sufficient for file-management operations that should be restricted to the file owner or an administrator. This issue is fixed in version 26.7.0.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Acceso en red (AV:N) con privilegios (PR:L) sin interacción. Un usuario compartido con acceso ordinario escalona a acciones de propietario (eliminación, reset, creación de claves) aprovechando validación débil de autorización (CWE-862), logrando control elevado de la cuenta/archivo.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
