{"id":"CVE-2026-71542","published":"2026-10-01T20:17:29.430","lastModified":"2026-10-01T20:23:46.493","description":"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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://github.com/GetSimpleCMS-CE/GetSimpleCMS-CE/security/advisories/GHSA-vqfh-838q-xfqh","tags":[]},{"url":"https://github.com/GetSimpleCMS-CE/GetSimpleCMS-CE/security/advisories/GHSA-vqfh-838q-xfqh","tags":[]}],"exploitRefs":[{"url":"https://github.com/GetSimpleCMS-CE/GetSimpleCMS-CE/security/advisories/GHSA-vqfh-838q-xfqh","tags":[]},{"url":"https://github.com/GetSimpleCMS-CE/GetSimpleCMS-CE/security/advisories/GHSA-vqfh-838q-xfqh","tags":[]}],"hasPoc":true,"ai":null}
