CVE-2026-24958Network attack vector

DOM-based XSS via unescaped widget JSON attributes

Published Feb 3, 2026 · Updated Feb 3, 2026

DOM-based XSS in Crocoblock JetElements 2.7.12.2 and earlier allows remote authenticated users to inject scripts into site pages. Multiple widgets place contributor-controlled JSON data-settings values into generated HTML without adequate sanitization or attribute escaping, allowing the browser to interpret crafted data as executable markup. Contributor access is required, and exploitation succeeds only after a privileged user interacts with the crafted content; script execution is confined to that visitor's browser context.
