CVE-2026-15630

Estado: AplazadaCrítica (9.9)—

A non-global organization admin in one tenant can bypass tenant boundaries to delete, create, or modify resources in any other tenant by exploiting a mismatch between authorization (based on ?id=) and action (based on request body).

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.

Vector CVSS con AV:N y PR:L indica acceso de red con privilegios de usuario (no administrador global), explotando validación deficiente de límites de tenant para escalar permisos y modificar recursos en otros tenants. CWE-863 (autorización débil) confirma T1078/T1068.

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.
