{"schema":"threatline.record/2","record":{"id":"CVE-2026-71542","aliases":["GHSA-vqfh-838q-xfqh"],"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.","categories":["Unclassified"],"product":"GetSimpleCMS-CE","vendor":"GetSimpleCMS-CE","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-71542","source_modified_at":"2026-10-01T19:51:29.324Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"GetSimpleCMS-CE","vendor":"GetSimpleCMS-CE","versions":[{"status":"affected","version":"<= 3.3.22"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/GetSimpleCMS-CE/GetSimpleCMS-CE/security/advisories/GHSA-vqfh-838q-xfqh","source_modified_at":"2026-08-07T07:58:29Z","fetched_at":"2026-10-24T18:03:20.872036Z","package":{"name":"GetSimpleCMS-CE","ecosystem":null},"range":"<= 3.3.22"}],"fixed_versions":[],"cvss":8.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00398,"percentile":0.32834,"score_date":"2026-10-23"},"published_at":"2026-10-01T19:40:04.001Z","modified_at":"2026-10-01T19:51:29.324Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-71542","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-01T19:51:29.324Z"},{"source":"GitHub Advisory Database","url":"https://github.com/GetSimpleCMS-CE/GetSimpleCMS-CE/security/advisories/GHSA-vqfh-838q-xfqh","fetched_at":"2026-10-24T18:03:20.872036Z","source_modified_at":"2026-08-07T07:58:29Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-71542","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-vqfh-838q-xfqh","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":"partial","assessed_at":"2026-10-01T19:51:10.583264Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-01T19:51:29.324Z","content_hash":"6cfe08c782ca09c92e0c6629a7c4174cffd243ab03337bd37ecb380a70d22b44"}}
