CVE-2024-22591Public exploitNetwork attack vector

Unauthorized group changes via tokenless cross-origin POST

Published Jan 18, 2024 · Updated Jun 20, 2025

CSRF in FlyCms 1.0 allows remote attackers to submit unauthorized user-group changes through /system/user/group_save. The group_save handler accepts a cross-origin POST containing groupName and group-policy fields without a request-bound anti-CSRF token. Exploitation requires a victim browser carrying an authorized FlyCms session to load attacker-controlled content, causing the browser to create or alter a group with the submitted values.
