CVE-2022-4544 – MashShare < 3.8.7 - Contributor+ Stored XSS

https://notcve.org/view.php?id=CVE-2022-4544

The MashShare WordPress plugin before 3.8.7 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 MashShare de WordPress anterior a 3.8.7 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 almacenado que podrían usarse contra usuarios con privilegios elevados, como administradores. The Social Media Share Buttons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via shortcode in versions up to, and including, 3.8.6 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/96e34d3d-627f-42f2-bfdb-c9d47dbf396c • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
