Publication date: 2026-07-11

Last updated on: 2026-07-11

Assigner: Wordfence

Description
The White Label CMS plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 2.7.12 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 White Label CMS plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in all versions up to and including 2.7.12. This vulnerability arises from 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 installations and installations where the unfiltered_html setting has been disabled.

Impact Analysis

This vulnerability allows attackers with admin-level access to inject malicious scripts that execute in the context of users visiting the affected pages.

Such script execution can lead to theft of user credentials, session hijacking, or other malicious actions that compromise the security and integrity of the affected WordPress site.

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