Estado: AnalizadaAlta (8.5)—

GitLab has remediated an issue in GitLab EE affecting all versions from 19.1 before 19.1.4 and 19.2 before 19.2.2 that under certain conditions could have allowed an authenticated user to cause AI usage to be attributed to another namespace, due to improper authorization of identity information supplied in requests.

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 AV:N/PR:L indica acceso remoto autenticado (T1210). La vulnerabilidad permite falsificar identidad en solicitudes para atribuir uso de IA a otro namespace, impactando integridad de datos (T1565.002) y manipulación de registros/atribuciones (T1578.004).

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.
