FKIE_CVE-2026-5169

Vulnerability from fkie_nvd - Published: 2026-04-08 07:16 - Updated: 2026-07-24 20:10
Summary
The Inquiry Form to Posts or Pages plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Form Header' field in versions up to and including 1.0. This is due to insufficient input sanitization when saving via update_option() and lack of output escaping when displaying the stored value. The vulnerability exists in two locations: (1) the plugin settings page at inq_form.php line 180 where the value is echoed into an HTML attribute without esc_attr(), and (2) the front-end shortcode output at inquery_form_to_posts_or_pages.php line 139 where the value is output in HTML content without esc_html(). This makes it possible for authenticated attackers with administrator-level access to inject arbitrary web scripts that will execute whenever a user accesses the plugin settings page or views a page containing the [inquiry_form] shortcode.

      "value": "El plugin Inquiry Form to Posts or Pages para WordPress es vulnerable a cross-site scripting almacenado a trav\u00e9s del campo \u0027Form Header\u0027 en versiones hasta la 1.0 inclusive. Esto se debe a una sanitizaci\u00f3n de entrada insuficiente al guardar a trav\u00e9s de update_option() y a la falta de escape de salida al mostrar el valor almacenado. La vulnerabilidad existe en dos ubicaciones: (1) la p\u00e1gina de configuraci\u00f3n del plugin en inq_form.PHP l\u00ednea 180 donde el valor se imprime en un atributo HTML sin esc_attr(), y (2) la salida del shortcode en el front-end en inquery_form_to_posts_or_pages.PHP l\u00ednea 139 donde el valor se muestra en contenido HTML sin esc_html(). Esto hace posible que atacantes autenticados con acceso de nivel de administrador inyecten scripts web arbitrarios que se ejecutar\u00e1n cada vez que un usuario acceda a la p\u00e1gina de configuraci\u00f3n del plugin o vea una p\u00e1gina que contenga el shortcode [inquiry_form]."
