# CVE-2026-23622: CSRF Protection Bypass: Sensitive endpoints accept GET requests, enabling admin account takeover

- Also known as: GHSA-54V4-4685-VWRJ
- Severity: CVSS 7.4 (High), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P
- CISA SSVC: exploitation=poc, automatable=yes, technicalImpact=total
- Known exploited (CISA KEV): no
- Published: 2026-01-15 · Updated: 2026-01-15

## Affected

- alextselegidis easyappointments: through 1.5.2
- alextselegidis/easyappointments (Packagist): through 1.5.2

## Description

Easy!Appointments is a self hosted appointment scheduler. In 1.5.2 and earlier, 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.
