CSRF Protection Bypass: Sensitive endpoints accept GET requests, enabling admin account takeover
Easy!Appointments is a self hosted appointment scheduler. In 1.5.2 and earlier, application/core/EASecurity.php::csrfverify() only enforces CSRF for POST requests and returns early for non-POST methods. Several application endpoints perform state-changing operations while accepting parameters from GET (or $_REQUEST), so an attacker can perform CSRF by forcing a victim's browser to issue a crafted GET request. Impact: creation of admin accounts, modification of admin email/password, and full admin account takeover.
