CVE-2024-2233Public exploitNetwork attack vector

Group membership changes via missing CSRF checks

Published Jul 3, 2024 · Updated Aug 1, 2024

Cross-site request forgery in 2code Himer before 2.1.1 allows remote attackers to change group membership through a logged-in user. Group actions exposed through WordPress admin-ajax.php, including wpqa_leave_group, accept state-changing POST requests without CSRF checks. A victim must be logged in and open attacker-controlled HTML; successful requests can accept or decline invitations or remove the victim from a group.
