CVE-2026-68490

Estado: Pendiente de análisisAlta (8.2)—

Incorrect permission assignment allows local users to obtain sensitive CalDAV/CardDAV information belonging to other accounts.

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.

AV:L/PR:L sin UI indica escalada local de privilegios (T1068). CWE-732 permite leer datos sensibles (CalDAV/CardDAV) de otras cuentas, impactando confidencialidad (T1005, T1552.001).

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.
