Estado: AnalizadaAlta (7.5)—

An issue has been discovered in GitLab CE/EE affecting all versions from 11.6 before 17.10.7, 17.11 before 17.11.3, and 18.0 before 18.0.1. A Discord webhook integration may cause DoS.

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/AC:L/PR:N/UI:N indica vulnerabilidad de red sin autenticación; CWE-770 (asignación excesiva de recursos) y descripción de DoS mediante webhook Discord confirman denegación de servicio por consumo de recursos.

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.
