{"id":"CVE-2026-71426","summary":"GetSimple CMS: Authenticated Stored Local File Inclusion (LFI) via page \"template\" field","details":"GetSimple CMS is a content management system (CMS), and GetSimple CMS CE is the community edition of that CMS. In versions 3.3.22 and prior, an authenticated user with page-editing rights can store an arbitrary filesystem path in a page's template attribute. On the public front-end, this value is passed unsanitized to a PHP include() when the page is rendered. Because the include path is never confined, this allows directory-traversal Local File Inclusion: arbitrary local files are included (and, if they contain PHP, executed) when any visitor requests the page. At time of publication, there are no publicly available patches.","aliases":["GHSA-559q-hqrv-m84x"],"modified":"2026-10-03T03:31:05.505370636Z","published":"2026-10-01T19:39:29.439Z","database_specific":{"cwe_ids":["CWE-22","CWE-98"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71426.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71426.json"},{"type":"ADVISORY","url":"https://github.com/GetSimpleCMS-CE/GetSimpleCMS-CE/security/advisories/GHSA-559q-hqrv-m84x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-71426"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/getsimplecms-ce/getsimplecms-ce","events":[{"introduced":"0"},{"last_affected":"5486c10c75111e93404413fea6408f53dbffd930"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"3.3.22"}],"source":"AFFECTED_FIELD"}}],"versions":["v3.3.22","v3.3.21","v3.3.17","v3.3.18.1","v3.3.16"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-71426.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
