Assigner: Wordfence

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.

Executive Summary

The vulnerability exists in the Team Members – Multi Language Supported Team Plugin for WordPress, affecting all versions up to and including 8.7. It is a Stored Cross-Site Scripting (XSS) flaw caused by insufficient input sanitization and output escaping in the admin settings.

Authenticated attackers with administrator-level permissions or higher can exploit this vulnerability to inject arbitrary web scripts into pages. These scripts execute whenever a user accesses the injected page.

This vulnerability specifically affects multi-site WordPress installations and installations where the unfiltered_html capability has been disabled.

Impact Analysis

This vulnerability can allow an attacker with administrator-level access to inject malicious scripts that execute in the context of other users visiting the affected pages.

Such script execution can lead to theft of sensitive information, session hijacking, or performing actions on behalf of other users without their consent.

Because the vulnerability requires high privileges and affects multi-site or restricted HTML installations, the impact is somewhat limited but still significant in those environments.
