CVE-2024-6778

Estado: AnalizadaAlta (7.5)—💥 PoC

Race in DevTools en Google Chrome anterior a 126.0.6478.182 permitió que un atacante convenciera a un usuario de instalar una extensión maliciosa para inyectar scripts o HTML en una página privilegiada a través de una extensión de Chrome manipulada. (Severidad de seguridad de Chrome: alta)

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
