CVE-2025-30516

Estado: AnalizadaAlta (7.5)—

Mattermost Mobile Apps versions <=2.25.0 fail to terminate sessions during logout under certain conditions (e.g. poor connectivity), allowing unauthorized users on shared devices to access sensitive notification content via continued mobile notifications

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Puntuación base: 7.5

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.27%
Percentil entre todas las CVEs puntuadas: 18
Fecha de la puntuación: 3/10/2026

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.

ExplotaciónT1190 Exploit Public-Facing Applicationinitial access45 %
Impacto principalT1078 Valid Accountsstealth · persistence · privilege escalation · initial access75 %
Impacto secundarioT1552.007 Container APIcredential access70 %

AV:N/PR:N permite T1190, pero el vector apunta a acceso no autenticado a aplicación expuesta. El impacto principal es acceso a cuenta (T1078) por sesiones no terminadas; secundario, lectura de datos sensibles (notificaciones) vía T1552.007.

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.
