{"id":"CVE-2026-71542","summary":"GetSimple CMS: Stored Cross-Site Scripting (XSS) via the \"title\" parameter in admin/components.php","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, GetSimpleCMS-CE is vulnerable to stored Cross-Site Scripting (XSS) in the \"Theme to Components\" functionality (admin/components.php) via the title parameter. The stored title is rendered inside a double-quoted HTML attribute in the administrative interface through an output path that HTML-entity-decodes the value before printing it, without re-encoding for the attribute context. This allows persistent execution of arbitrary JavaScript in the admin panel. At time of publication, there are no publicly available patches.","aliases":["GHSA-vqfh-838q-xfqh"],"modified":"2026-10-03T03:31:02.726483919Z","published":"2026-10-01T19:40:04.001Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71542.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71542.json"},{"type":"ADVISORY","url":"https://github.com/GetSimpleCMS-CE/GetSimpleCMS-CE/security/advisories/GHSA-vqfh-838q-xfqh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-71542"}],"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-2026-71542.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
