CVE-2026-100158
El complemento SQL Chart Builder para WordPress es vulnerable a Cross-Site Scripting almacenado (XSS) a través del parámetro 'X-axis column value ($value->$xarg_s from $wpdb->get_results())' en todas las versiones hasta la 3.0.6 inclusive, debido a una desinfección insuficiente de la entrada y a un escapado insuficiente de la salida. Esto permite que atacantes autenticados, con acceso de nivel Subscriber y superiores, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página infectada.
Leer descripción completaMostrar menos
Para ello se requiere que un administrador haya publicado un gráfico cuya consulta SQL devuelva una columna controlable por un usuario con menos privilegios, como wp_users.display_name, que un Subscriber puede rellenar con una carga útil a través de la página de perfil estándar de WordPress en /wp-admin/profile.php.

"value": "The SQL Chart Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'X-axis column value ($value->$xarg_s from $wpdb->get_results())' parameter in all versions up to, and including, 3.0.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires an administrator to have published a chart whose SQL query returns a column controllable by a lower-privileged user, such as wp_users.display_name, which a Subscriber can populate with a payload via the standard WordPress profile page at /wp-admin/profile.php."
