CVE-2025-6754

Estado: AplazadaAlta (8.8)—

The SEO Metrics plugin for WordPress is vulnerable to Privilege Escalation due to missing authorization checks in both the seo_metrics_handle_connect_button_click() AJAX handler and the seo_metrics_handle_custom_endpoint() function in all versions up to, and including, 1.0.15. Because the AJAX action only verifies a nonce, without checking the caller’s capabilities, a subscriber-level user can retrieve the token and then access the custom endpoint to obtain full administrator cookies.

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Acceso remoto a servicio (AJAX) con PR:L sin UI. Impactos: obtención de cookies de admin (T1078) y manipulación de cuenta de administrador (T1098).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
