CVE-2020-26411

Estado: ModificadaMedia (4.3)—

Se detectó una posible vulnerabilidad de DOS en todas las versiones de Gitlab desde 13.4.x (versiones anteriores 13.4 e incluyéndola a versiones posteriores 13.4.7, versiones anteriores a 13.5 incluyéndola a versiones posteriores a 13.5.5 y versiones anteriores a 13.6 incluyéndola a versiones posteriores a 13.6.2). Usando un nombre de consulta específico para la búsqueda de un proyecto puede causar tiempos de espera de sentencia que pueden conllevar a un DOS potencial si es abusado

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).
