CVE-2022-22779

Estado: ModificadaBaja (3.7)—

Los clientes de Keybase para macOS y Windows anteriores a la versión 5.9.0 no eliminan correctamente los mensajes explotados iniciados por un usuario. Esto puede ocurrir si el usuario receptor cambia a una función que no sea de chat y coloca el host en un estado de suspensión antes de que el usuario emisor explote los mensajes. Esto podría conllevar a una divulgación de información confidencial que debía ser eliminada del sistema de archivos de un usuario

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).
