CVE-2023-6382

The Master Slider – Responsive Touch Slider plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'ms_slide' shortcode in all versions up to, and including, 3.9.9 due to insufficient input sanitization and output escaping on user supplied 'css_class' attribute. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. > MITRE Terms of Use apply – see LICENSE‑MITRE.txt
