CVE-2021-39942

Estado: ModificadaMedia (6.5)—

Una vulnerabilidad de denegación de servicio en GitLab CE/EE que afecta a todas las versiones a partir de la 12.0 anteriores a 14.3.6, a todas las versiones a partir de la 14.4 anteriores a 14.4.4, a todas las versiones a partir de la 14.5 anteriores a 14.5.2, permite a usuarios poco privilegiados omitir los límites de tamaño de los archivos en el repositorio de paquetes NPM para causar potencialmente una denegación de servicio

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).
