CVE-2026-28657

Estado: AnalizadaAlta (7.8)—

In onActivityResult of AppWidgetConfigActivityProxy.java, there is a possible unauthorized URI permission grant due to a confused deputy. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

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 local (AV:L) sin interacción del usuario permite escalada de privilegios (PR:L→root) mediante confused deputy en AppWidgetConfigActivityProxy. El impacto principal es T1548.004 (abuso de funcionalidad de delegación de permisos de URI en Android); secundariamente acceso a datos sensibles (C:H)

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.
