{"id":"CVE-2026-33061","summary":"Jexactyl has Stored DOM Cross-Site Scripting (XSS) via unescaped JSON in Blade template","details":"Jexactyl is a customisable game management panel and billing system. Commits after 025e8dbb0daaa04054276bda814d922cf4af58da and before e28edb204e80efab628d1241198ea4f079779cfd inject server-side objects into client-side JavaScript through resources/views/templates/wrapper.blade.php. Using unescaped {!! json_encode(...) !!} without safe encoding flags  allows string values to break out of the JavaScript context and be interpreted as HTML/JS by the browser. If any serialized fields contain attacker-controlled content, such as a username, display name, or site config value, a malicious payload will execute arbitrary script for any user viewing the page (stored DOM XSS). This issue has been patched by commit  e28edb204e80efab628d1241198ea4f079779cfd.","aliases":["GHSA-6xgw-mmmv-57h2"],"modified":"2026-10-28T02:30:49.038320023Z","published":"2026-03-20T07:34:14.077Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33061.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33061.json"},{"type":"ADVISORY","url":"https://github.com/Jexactyl/Jexactyl/security/advisories/GHSA-6xgw-mmmv-57h2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33061"},{"type":"FIX","url":"https://github.com/Jexactyl/Jexactyl/commit/e28edb204e80efab628d1241198ea4f079779cfd"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/jexactyl/jexactyl","events":[{"introduced":"025e8dbb0daaa04054276bda814d922cf4af58da"},{"fixed":"e28edb204e80efab628d1241198ea4f079779cfd"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StringRangeExpression","range":[{"introduced":"025e8dbb0daaa04054276bda814d922cf4af58da"},{"fixed":"e28edb204e80efab628d1241198ea4f079779cfd"}]},{"range":[{"fixed":"e28edb204e80efab628d1241198ea4f079779cfd"}],"source":"REFERENCES_COMMIT"}]}}],"versions":["4.0.0-beta1","4.0.0-beta2","4.0.0-beta3","4.0.0-beta4","4.0.0-beta5","4.0.0-beta6","4.0.0-beta7","4.0.0-rc1","4.0.0-rc2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33061.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:N"}]}
