CVE-2026-10553
The jQuery Hover Footnotes plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.4. This is due to missing or incorrect nonce validation on the jqFootnotes_options_subpanel function. This makes it possible for unauthenticated attackers to update the plugin's settings with arbitrary values that, because option values such as jqfoot_anchor_open, jqfoot_anchor_close, and jqfoot_title are echoed unescaped into frontend page content, can be chained into persistent Cross-Site Scripting affecting all site visitors via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. Successful exploitation of the CSRF vulnerability can be chained into stored Cross-Site Scripting, as the overwritten option values are persisted via update_option() without sanitization and rendered unescaped on the frontend.

"value": "El plugin jQuery Hover Footnotes para WordPress es vulnerable a falsificación de petición en sitios cruzados en todas las versiones hasta la 1.4, inclusive. Esto se debe a la validación de nonce faltante o incorrecta en la función jqFootnotes_options_subpanel. Esto hace posible que atacantes no autenticados actualicen la configuración del plugin con valores arbitrarios que, debido a que los valores de opción como jqfoot_anchor_open, jqfoot_anchor_close y jqfoot_title se muestran sin escapar en el contenido de la página del frontend, pueden encadenarse en un cross-site scripting persistente que afecta a todos los visitantes del sitio a través de una petición falsificada, siempre que puedan engañar a un administrador del sitio para que realice una acción como hacer clic en un enlace. La explotación exitosa de la vulnerabilidad CSRF puede encadenarse en un cross-site scripting almacenado, ya que los valores de opción sobrescritos se persisten a través de update_option() sin sanitización y se renderizan sin escapar en el frontend."
