CVE-2026-89424

Estado: AplazadaMedia (6.4)—

The Duplicate Post plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'noti_token' parameter in all versions up to, and including, 1.5.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires that the site owner has enabled the plugin's User Level Permissions for the Subscriber role, as this grants access to the i_saw_this_noti AJAX branch needed to deliver the payload.

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.

AV:N sin privilegios (aunque requiere subscriber) en aplicación web (plugin WordPress); CWE-79 XSS almacenado permite inyección de scripts. El parámetro 'noti_token' sin sanitización permite ejecución de código JavaScript en navegadores de otros usuarios.

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.
