Estado: AplazadaAlta (8.7)—

A remote, authenticated, non-admin Craft CMS Control Panel user with only the accessCp permission can execute operating system commands as the PHP web worker.

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:N/PR:L sin UI permite a usuario autenticado remoto ejecutar comandos del SO como worker PHP; escala privilegios desde rol limitado (solo accessCp) a ejecución de código del servidor.

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.
