CVE-2026-94264 Details
Description
The Advanced Custom Fields: Extended WordPress plugin before 0.9.2.8, Advanced Custom Fields: Extended PRO WordPress plugin before 0.9.2.8 does not validate or escape some of its form shortcode attributes, which can be pointed at values taken from the visitor's own request and are then output without escaping, allowing users with a role as low as contributor to have arbitrary script run in the browser of anyone led to open a crafted link or page, including a logged-in administrator. This is an incomplete fix for CVE-2023-5292, whose deny-list covers only the three HTML wrapper attributes.
A cross-site scripting (XSS) vulnerability has been identified in the Advanced Custom Fields: Extended WordPress plugin versions prior to 0.9.2.8, as well as in the Advanced Custom Fields: Extended PRO WordPress plugin versions prior to 0.9.2.8. The vulnerability arises because the plugins do not properly validate or escape certain form shortcode attributes. These attributes can be manipulated to include values from the visitor's request and are then output without proper escaping. This flaw allows users with a minimum role of contributor to execute arbitrary scripts in the browsers of those who open a crafted link or page, potentially affecting logged-in administrators. This vulnerability is an incomplete fix for CVE-2023-5292, as the deny-list only addresses three HTML wrapper attributes.
Users are advised to update to version 0.9.2.8 or later.
