CVE-2022-40489Public exploitNetwork attack vector

Super-administrator creation via forged admin request

Published Dec 1, 2022 · Updated Apr 24, 2025

CSRF in ThinkCMF 6.0.7 allows remote attackers to create a super-administrator account through an authenticated administrator's browser. The /admin/user/addpost.html handler accepts a cross-origin POST containing attacker-chosen login, password, email, and administrator role values without a CSRF token. Exploitation requires a logged-in administrator to visit an attacker-controlled page; the resulting credentials grant control of the site.
