CVE-2026-11898: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in videousermanuals White Label CMS
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.
AI Analysis
Technical Summary
CVE-2026-11898 is a stored cross-site scripting vulnerability in the White Label CMS WordPress plugin (videousermanuals) affecting versions up to 2.7.12. The flaw is due to improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of admin settings input. This allows authenticated administrators on multi-site WordPress installations or installations with unfiltered_html disabled to inject malicious scripts that execute in the context of users visiting the affected pages. The vulnerability does not affect single-site installations or those with unfiltered_html enabled.
Potential Impact
An attacker with administrator-level privileges on affected WordPress multi-site installations can inject persistent malicious scripts via admin settings. These scripts execute in the browsers of users who visit the injected pages, potentially leading to data theft, session hijacking, or other client-side attacks. The vulnerability does not impact availability and requires high privileges and specific configuration to exploit.
Mitigation Recommendations
No official patch or fix has been confirmed for this vulnerability as of the provided data. Users should monitor the vendor's advisory for updates. Until a fix is available, restrict administrator access to trusted users only and consider enabling unfiltered_html capability if feasible. Since this affects only multi-site installations or those with unfiltered_html disabled, single-site users or those with unfiltered_html enabled are not impacted. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
