CVE-2026-2933Public exploitNetwork attack vector

Stored script execution via unneutralized ad name

Published Feb 22, 2026 · Updated Feb 22, 2026

Stored cross-site scripting in YiFang CMS 2.0.0 through 2.0.5 allows remote authenticated users to inject script through an ad Name value. The update function in app/db/admin/D_adManage.php stores the Name argument without neutralizing it before the Extended Management Module renders the value. Administrative privileges are required to submit the value, and another user's interaction executes the stored script in that user's browser, enabling page-content modification and access to browser-readable data.
