Estado: AnalizadaCrítica (9.9)—

An issue has been discovered in GitLab CE/EE affecting all versions from 17.11 before 17.11.4 and 18.0 before 18.0.2. A missing authorization check may have allowed compliance frameworks to be applied to projects outside the compliance framework's group.

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.

CWE-862 (falta de autorización) en GitLab con acceso en red requiriendo autenticación (PR:L) permite aplicar marcos de cumplimiento fuera de su grupo, escalando permisos y manipulando datos.

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.
