CVE-2024-8720

RumbleTalk Live Group Chat – HTML5 <= 6.3.0 - Authenticated (Contributor+) Stored Cross-Site Scripting

6.4 Medium

The RumbleTalk Live Group Chat – HTML5 plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'rumbletalk-admin-button' shortcode in all versions up to, and including, 6.3.0 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
