      "value": "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\u0027s 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 falsificaci\u00f3n de petici\u00f3n en sitios cruzados en todas las versiones hasta la 1.4, inclusive. Esto se debe a la validaci\u00f3n de nonce faltante o incorrecta en la funci\u00f3n jqFootnotes_options_subpanel. Esto hace posible que atacantes no autenticados actualicen la configuraci\u00f3n del plugin con valores arbitrarios que, debido a que los valores de opci\u00f3n como jqfoot_anchor_open, jqfoot_anchor_close y jqfoot_title se muestran sin escapar en el contenido de la p\u00e1gina del frontend, pueden encadenarse en un cross-site scripting persistente que afecta a todos los visitantes del sitio a trav\u00e9s de una petici\u00f3n falsificada, siempre que puedan enga\u00f1ar a un administrador del sitio para que realice una acci\u00f3n como hacer clic en un enlace. La explotaci\u00f3n exitosa de la vulnerabilidad CSRF puede encadenarse en un cross-site scripting almacenado, ya que los valores de opci\u00f3n sobrescritos se persisten a trav\u00e9s de update_option() sin sanitizaci\u00f3n y se renderizan sin escapar en el frontend."
