CVE-2026-3743Network attack vector

Cross-site scripting via unneutralized page-group name

Published Mar 8, 2026 · Updated Mar 8, 2026

Cross-site scripting in YiFang CMS 2.0.5 allows remote authenticated users to inject script through a crafted page-group Name value. The update function in app/db/admin/D_singlePageGroup.php fails to neutralize the Name argument for page generation; the exact statement and output context are undisclosed. Low-privileged access and a later user's page view are required, limiting the demonstrated consequence to attacker-controlled script execution in that viewer's browser.
