CVE-2023-46943

Estado: ModificadaCrítica (9.1)—

Se descubrió un problema en el paquete @evershop/evershop de NPM antes de la versión 1.0.0-rc.8. El secreto HMAC utilizado para generar tokens está codificado como "secret". Un secreto HMAC débil representa un riesgo porque los atacantes pueden usar el secreto predecible para crear tokens web JSON (JWT) válidos, lo que les permite acceder a información y acciones importantes dentro de la aplicación.

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).
