CVE-2026-12114
Team Members <= 8.7 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'custom_css' Parameter
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 makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
