CVE-2023-53953Public exploitNetwork attack vector

Stored XSS via unsanitized page titles

Published Dec 19, 2025 · Updated Dec 19, 2025

Stored XSS in WebsiteBaker CMS 2.13.3 allows remote authenticated users to execute JavaScript in other users' browsers via page titles. The page-creation handler at /admin/pages/add.php stores the title parameter without neutralizing HTML event-handler markup, and the frontend later renders that title. Page-creation permission is required, and impact begins only when another user views the crafted public page, exposing that user's browser context to script-driven reads or actions.
