CVE-2025-3153Network attack vector

Stored XSS via unsanitized countryless address output

Published Apr 3, 2025 · Updated Apr 3, 2025

Stored XSS in the Address attribute in Concrete CMS before 8.5.20 and 9.0.0 through 9.4.0RC1 allows remote authenticated users to run script. AddressValue's HTML formatter returns countryless address fields without applying output escaping, so saved markup is rendered in a dashboard page. An attacker must have site-admin-granted permission to fill an address attribute, and viewing the stored value can disclose limited data, permit limited modification, or make the dashboard page unavailable.
