Concrete CMS vulnerable to stored XSS via the Role Name field

  • Disclosed: 09.02.2024
  • Updated: 11.10.2026 10:22

Concrete CMS version 9 before 9.2.5 is vulnerable to  stored XSS via the Role Name field since there is insufficient validation of administrator provided data for that field. A rogue administrator could inject malicious code into the Role Name field which might be executed when users visit the affected page. The Concrete CMS Security team scored this 2 with CVSS v3 vector AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:L/A:N https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator . Concrete versions below 9 do not include group types so they are not affected by this vulnerability.
