CVE-2026-2994
Concrete CMS vulnerable to Cross-Site Request Forgery (CSRF)
Impact
Concrete CMS below version 9.4.8 is subject to CSRF by a Rogue Administrator using the Anti-Spam Allowlist Group Configuration via group_id parameter which can leads to a security bypass since changes are saved prior to checking the CSRF token. The Concrete CMS security team thanks z3rco for reporting
