Master Slider – Responsive Touch Slider <= 3.9.10 - Authenticated (Contributor+) Stored Cross-Site Scripting via ms_layer Shortcode

Description The Master Slider – Responsive Touch Slider plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin’s ‘ms_layer’ shortcode in all versions up to, and including, 3.9.10 due to insufficient input sanitization and output escaping on the ‘css_id’ user supplied attribute. 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. e CVE-2024-37222 may be a duplicate of this issue.
