CVE-2021-26543

Estado: ModificadaAlta (8.8)—

La función "gitDiff" en Wayfair git-parse versiones anteriores o iguales a 1.0.4 tiene una vulnerabilidad de inyección de comandos. Los clientes de la biblioteca git-parse probablemente no sean conscientes de ello, por lo que podrían escribir involuntariamente código que contenga una vulnerabilidad. El problema se ha resuelto en la versión 1.0.5.

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).
