What is CVE-2025-11737?

The VK All in One Expansion Unit plugin for WordPress is susceptible to a Stored Cross-Site Scripting vulnerability due to inadequate input sanitization and output escaping. This flaw allows authenticated users, with Contributor-level access and higher, to inject arbitrary web scripts via the 'vkExUnit_sns_title' parameter. The injected scripts are executed whenever a user accesses a page containing the malicious code, exposing users to potential attacks and compromising the integrity of the website.
