CVE-2026-11898: Videousermanuals White Label CMS

Medium severity, CVSS 4.4. EPSS: 0.4% chance of exploitation in the next 30 days.

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.
