CVE-2026-0557

The WP Data Access plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'wpda_app' shortcode in all versions up to, and including, 5.5.63 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Summary		(es) El plugin WP Data Access para WordPress es vulnerable a cross-site scripting almacenado a través del shortcode 'wpda_app' del plugin en todas las versiones hasta la 5.5.63, inclusive, debido a la sanitización insuficiente de la entrada y al escape de la salida en los atributos proporcionados por el usuario. Esto hace posible que atacantes autenticados, con nivel de acceso de colaborador y superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada.
