CVE-2026-23622Public exploitNetwork attack vector

Administrator takeover via non-POST CSRF bypass

Published Jan 15, 2026 · Updated Jan 15, 2026

CSRF in Easy!Appointments 1.5.2 and earlier allows remote attackers to take over an administrator account through a crafted GET request. EA_Security.php::csrf_verify() returns before token validation for non-POST methods, while sensitive controllers accept GET or $_REQUEST parameters and still perform state changes. An authenticated administrator must visit attacker-controlled content; the resulting request can create an administrator or replace administrator email and password.
