Vulnerabilidad · Publicado 03/10/2026
El plugin SEOPress para WordPress es vulnerable a inyección de scripts maliciosos (XSS almacenado) a través del campo de nombre de autor, permitiendo a atacantes sin autenticación ejecutar código arbitrario en páginas afectadas. La vulnerabilidad impacta todos los sitios WordPress que utilicen versiones 10.2 o anteriores del plugin, especialmente aquellos con múltiples usuarios o perfiles públicos visibles.
The SEOPress – AI SEO Plugin & On-site SEO plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Author Display Name in all versions up to, and including, 10.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires the 'Track Authors' custom dimension to be configured in the plugin's Google Analytics 4 or Matomo settings, and the attacker must be able to publish public singular content (e.g., via bbPress forum topics) so that the injected display name is rendered in the tracking script.
