Descriptions

The Simple Blog Card WordPress plugin before 1.31 does not validate and escape some of its shortcode attributes before outputting them back in a page/post where the shortcode is embed, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks

El plugin de WordPress Simple Blog Card anterior a la versión 1.31 no valida y escapa de algunos de sus atributos de shortcode antes de devolverlos a una página/publicación en la que el shortcode está incrustado, lo que podría permitir a los usuarios con el rol de colaborador y superior realizar ataques de Cross-Site Scripting (XSS) Almacenado.

The Simple Blog Card plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode in versions up to, and including, 1.30 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
