CVE-2022-4481 – Mesmerize Companion < 1.6.135 - Contributor+ Stored XSS

https://notcve.org/view.php?id=CVE-2022-4481

The Mesmerize Companion WordPress plugin before 1.6.135 does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks which could be used against high privilege users such as admins. El complemento Mesmerize Companion de WordPress anterior a 1.6.135 no valida ni escapa algunos de sus atributos de código corto antes de devolverlos a la página, lo que podría permitir a los usuarios con un rol tan bajo como colaborador realizar ataques de cross-site scripting que podrían usarse contra usuarios con privilegios elevados, como administradores. The Mesmerize Companion plugin for WordPress is vulnerable to Stored Cross-Site Scripting via shortcode in versions up to, and including, 1.6.133 due to insufficient input sanitization and output escaping. 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. • https://wpscan.com/vulnerability/9dc9d377-635d-4d4f-9916-33bcedbba6f0 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
