Affected packages

• Packagist concrete5/concrete5: < 9.4.8 → fixed in 9.4.8

Description

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
