CVE-2026-23622: alextselegidis/easyappointments is Vulnerable to CSRF Protection Bypass

application/core/EA_Security.php::csrf_verify() 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
