**Name of the Vulnerable Software and Affected Versions**
The Better Messages – Live Chat for WordPress, BuddyPress, PeepSo, Ultimate Member, BuddyBoss plugin for WordPress versions up to, and including, 2.6.9
**Description**
The issue is related to Stored Cross-Site Scripting via the plugin's 'better messages live chat button' shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. This allows 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.
**Recommendations**
For versions up to, and including, 2.6.9, update to a version that fixes the insufficient input sanitization and output escaping issue.

Avoid using the `better messages live chat button` shortcode in pages until the issue is resolved.
