CVE-2026-15897

Estado: AplazadaAlta (8.8)—

The Super Forms – Drag & Drop Form Builder plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 6.3.316. This is due to the Register & Login add-on's before_email_success_msg() function, in its register_login_action='update' flow, trusting an attacker-supplied user_id value and passing it to wp_update_user() without any ownership or capability check.

Leer descripción completaMostrar menos

Because the super_save_form AJAX action also enforces no capability check, any authenticated user with Subscriber-level access and above can create the required malicious form (register_login_action='update' with register_login_user_id_update='true') and then submit it with user_id set to an administrator's ID along with a new user_pass/user_email. This makes it possible for authenticated attackers with Subscriber-level access and above to overwrite the credentials of arbitrary existing accounts — including administrators — resulting in account takeover and full site compromise.

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.

Vulnerabilidad remota (AV:N, PR:L) en plugin WordPress que permite a usuarios autenticados modificar credenciales de administradores sin validación de propiedad. El ataque requiere autenticación previa y acceso a red (Subscriber+), típico de T1210. Impacto: modificación de cuentas existentes (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.
