{"id":"CVE-2026-23622","summary":"CSRF Protection Bypass: Sensitive endpoints accept GET requests, enabling admin account takeover","details":"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.","aliases":["GHSA-54v4-4685-vwrj"],"modified":"2026-08-12T03:51:28.745659544Z","published":"2026-01-15T19:28:58.369Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23622.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-352"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23622.json"},{"type":"ADVISORY","url":"https://github.com/alextselegidis/easyappointments/security/advisories/GHSA-54v4-4685-vwrj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23622"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/alextselegidis/easyappointments","events":[{"introduced":"0"},{"last_affected":"48d32686b0f40fc782c2bdf1bde4baafa4dbeea4"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"1.5.2"}],"source":["AFFECTED_FIELD","CPE_RANGE"],"cpe":"cpe:2.3:a:easyappointments:easy\\!appointments:*:*:*:*:*:-:*:*"}}],"versions":["1.5.2","1.5.2-beta.1","1.5.1","1.5.1-beta.1","1.5.0","1.5.0-beta.1","1.5.0-alpha.1","1.5.0-dev.4","1.5.0-dev.3","1.5.0-dev.2","1.5.0-dev.1","1.3.0-beta.2","1.3.0-beta.1","1.3.0-alpha.1","1.2.0-beta.1","1.2.0-alpha.1","1.1.0","1.1.0-beta.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-23622.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
