The Passster plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's content_protector shortcode in all versions up to, and including, 4.2.6.4 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.

The Qyrr WordPress plugin before 0.7 does not escape the data-uri of the QR Code when outputting it in a src attribute, allowing for Cross-Site Scripting attacks. Furthermore, the data_uri_to_meta AJAX action, available to all authenticated users, only had a CSRF check in place, with the nonce available to users with a role as low as Contributor allowing any user with such role (and above) to set a malicious data-uri in arbitrary QR Code posts, leading to a Stored Cross-Site Scripting issue. El complemento Qyrr WordPress anterior a 0.7 no escapa del uri de datos del código QR cuando lo genera en un atributo src, lo que permite ataques de cross site scripting. Además, la acción data_uri_to_meta AJAX, disponible para todos los usuarios autenticados, solo tenía una verificación CSRF implementada, y el nonce disponible para usuarios con un rol tan bajo como Colaborador permite que cualquier usuario con dicho rol (y superior) establezca un dato malicioso. uri en publicaciones de códigos QR arbitrarios, lo que genera un problema de cross site scripting almacenado.
