Estado: ModificadaMedia (4.3)—💥 Exploit

Vulnerabilidad de XSS en wp-includes/wp-db.php en WordPress en versiones anteriores a 4.2.1, permite a atacantes remotos inyectar secuencias de comandos web o HTML arbitrarios a través de un comentario largo que es almacenado indebidamente a causa de las limitaciones en el tipo de datos de MySQL TEXT.

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.
