CtrlPanel: Stored XSS in Admin Role Management via Unescaped DataTable HTML Output_CVE-2026-34246

{
    "lastseen": "",
    "description": "CtrlPanel is open-source billing software for hosting providers. Versions 1.1.1 and prior contain a Stored Cross-Site Scripting (XSS) vulnerability exists in the admin role management interface. In app/Http/Controllers/Admin/RoleController.php, the datatable() method interpolates $role->name and $role->color directly into a <span> element's HTML and style attribute without sanitization, and the chained .rawColumns(['actions', 'name']) call instructs DataTables to render the name column as raw HTML, bypassing automatic output escaping. An admin with role creation or edit permissions can inject a payload such as <img src=x onerror=\"alert('XSS_POC')\"> into the name or color fields, which is persisted to the database and executes in the browser of every admin who loads the /admin/roles page. This enables session hijacking via cookie theft, credential harvesting through fake login prompts or keyloggers, lateral privilege escalation by performing admin actions on behalf of victims, and a persistent backdoor that re-executes on every page load until the malicious role record is removed. This issue has been resolved in version 1.2.0.",
