CVE-2024-7394Network attack vector

Stored XSS via unencoded attribute-set names

Published Aug 8, 2024 · Updated Sep 25, 2025

Stored XSS in Concrete CMS before 8.5.18 and 9.0.0 through 9.3.2 allows remote authenticated users to run script in another user's browser. Attribute-set views rendered getAttributeSetName() output directly in an HTML heading and form value; crafted stored names therefore remained executable markup. Administrator privileges are required to save the name, and another user must open an affected view, allowing the script to read data available to that user's browser.
