Estado: ModificadaCrítica (9.8)—

Esto afecta al paquete js-ini versiones anteriores a 1.3.0. Si un atacante envía un archivo INI malicioso a una aplicación que lo analiza con parse , contaminará el prototipo de la aplicación. Esto puede ser explotado aún más dependiendo del contexto

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).
