CVE-2020-20093

Estado: ModificadaMedia (6.5)—💥 PoC

The Facebook Messenger app for iOS 227.0 and prior and Android 228.1.0.10.116 and prior user interface does not properly represent URI messages to the user, which results in URI spoofing via specially crafted messages.

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.
