CVE-2026-8354

Estado: AplazadaMedia (6.4)—

The Gum Addon for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'pop_tag' parameter in all versions up to, and including, 1.3.15 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

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.

XSS almacenado en parámetro 'pop_tag' con AV:N y PR:L permite inyección de scripts ejecutables. Vector CVSS y CWE-79 confirman impacto en ejecución de código del lado cliente.

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.
