CVE-2026-33061 Details
Description
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.
A stored DOM cross-site scripting vulnerability has been identified in the Jexactyl game management panel and billing system, specifically in the 'canary' version prior to the patch commit. The issue arises from the injection of unescaped server-side objects into client-side JavaScript via a Blade template. This vulnerability allows attacker-controlled content, such as usernames or site configuration values, to be executed as arbitrary scripts in the browser for any user viewing the page.
The vulnerability has been patched in the 'canary' version. Users should update to the latest version.
