Descriptions

The Gutenberg Blocks with AI by Kadence WP WordPress plugin before 3.2.37 does not validate and escape some of its block attributes before outputting them back in a page/post where the block is embed, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks

El complemento Gutenberg Blocks with AI by Kadence WP WordPress anterior a 3.2.37 no valida ni escapa algunos de sus atributos de bloque antes de devolverlos a una página/publicación donde está incrustado el bloque, lo que podría permitir a los usuarios con el rol de colaborador y superiores realizar ataques de Cross-Site Scripting almacenado

The Gutenberg Blocks with AI by Kadence WP – Page Builder Features plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the fileUrl attribute in versions up to, and including 3.2.36, due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
