Prior to version 1.5, the UpdateCE update form contained no anti-CSRF token, and the POST handler performed no token or request-origin verification. A remote attacker can host a page that auto-submits a forged POST to the update endpoint; when an authenticated administrator visits it, the server performs an attacker-directed download-and-deploy operation in the administrator's session — with no further interaction. Because the deployed content is executed (see the related ZIP-extraction advisory), this yields remote code execution. The url field is additionally written into the form unescaped, providing a secondary HTML-injection sink via a malicious upgrade.json. This issue has been patched in version 1.5.","state":0,"publishedAt":"2026-10-01T19:38:30.623+00:00","modifiedAt":"2026-10-06T02:07:29.187+00:00","affected":[{"ecosystem":"Vendor product","name":"GetSimpleCMS-CE","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"GetSimpleCMS-CE\",\n                    \"product\": \"GetSimpleCMS-CE\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.5\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","score":9.6,"severity":"CRITICAL"}],"references":["https://github.com/GetSimpleCMS-CE/GetSimpleCMS-CE/security/advisories/GHSA-2rxv-4g4m-573w"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-56662","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-56662","identifiers":["CVE-2026-56662"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
