FKIE_CVE-2025-11265

Vulnerability from fkie_nvd - Published: 2025-11-18 08:15 - Updated: 2025-11-18 14:06
Severity ?
6.4 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N
Summary
The VK All in One Expansion Unit plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'vkExUnit_cta_url' and 'vkExUnit_cta_button_text' parameters in all versions up to, and including, 9.112.1. This is due to a logic error in the CTA save function that reads sanitization callbacks from the wrong variable ($custom_field_name instead of $custom_field_options), causing the sanitization to never be applied. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that execute when a user accesses an injected page.",
