CVE-2017-5487

Estado: ModificadaMedia (5.3)—💥 Exploit

wp-includes/rest-api/endpoints/class-wp-rest-users-controller.php en la implementación REST API en WordPress 4.7 en versiones anteriores a 4.7.1 no restringe adecuadamente los listados de autores de publicación, lo que permite a atacantes remotos obtener información sensible a través de una petición wp-json/wp/v2/users.

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.
