Description

The Team Members – Multi Language Supported Team Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 8.7 due to insufficient input sanitization and output escaping.

This only affects multi-site installations and installations where unfiltered_html has been disabled.
