CVE-2025-13181Public exploitNetwork attack vector

Administrator-browser script execution via unencoded material names

Published Nov 14, 2025 · Updated Nov 14, 2025

Stored cross-site scripting in pojoin h3blog 1.0 allows remote authenticated users to execute JavaScript in an administrator's browser. The /admin/cms/material/add handler stores the Name field without sanitization, and the material-management view renders it without output encoding. Administrative access is required to submit the payload, which runs when an administrator opens the material list or management interface.
