{"schema":"threatline.record/2","record":{"id":"CVE-2026-56662","aliases":["GHSA-2rxv-4g4m-573w"],"summary":"GetSimple CMS: Missing CSRF protection in UpdateCE allows forging a privileged server-side update request","details":"GetSimple CMS is a content management system (CMS), and GetSimple CMS CE is the community edition of that CMS. 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.","categories":["Unclassified"],"product":"GetSimpleCMS-CE","vendor":"GetSimpleCMS-CE","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-56662","source_modified_at":"2026-10-06T02:07:29.187Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"GetSimpleCMS-CE","vendor":"GetSimpleCMS-CE","versions":[{"status":"affected","version":"< 1.5"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/GetSimpleCMS-CE/GetSimpleCMS-CE/security/advisories/GHSA-2rxv-4g4m-573w","source_modified_at":"2026-07-29T09:31:52Z","fetched_at":"2026-10-24T05:41:33.294140Z","package":{"ecosystem":"php","name":"UpdateCE"},"range":"<= 1.4"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/GetSimpleCMS-CE/GetSimpleCMS-CE/security/advisories/GHSA-2rxv-4g4m-573w","source_modified_at":"2026-07-29T09:31:52Z","fetched_at":"2026-10-24T05:41:33.294140Z","package":{"ecosystem":"php","name":"UpdateCE"},"version":"1.5"}],"cvss":9.6,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00216,"percentile":0.1137,"score_date":"2026-10-23"},"published_at":"2026-10-01T19:38:30.623Z","modified_at":"2026-10-06T02:07:29.187Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-56662","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-06T02:07:29.187Z"},{"source":"GitHub Advisory Database","url":"https://github.com/GetSimpleCMS-CE/GetSimpleCMS-CE/security/advisories/GHSA-2rxv-4g4m-573w","fetched_at":"2026-10-24T05:41:33.294140Z","source_modified_at":"2026-07-29T09:31:52Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-56662","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/GetSimpleCMS-CE/GetSimpleCMS-CE/security/advisories/GHSA-2rxv-4g4m-573w","tags":["exploit"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"total","assessed_at":"2026-10-06T02:07:05.762724Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-06T02:07:29.187Z","content_hash":"e1887f75afdef078e22029afeb90403bd96f7c90824471e6d16f2470d4ccffe4"}}
