Stored XSS via unescaped role DataTable output
Published May 19, 2026 · Updated May 19, 2026
Stored XSS in CtrlPanel 1.1.1 and earlier allows remote authenticated users to execute JavaScript in administrators' browsers. The RoleController datatable method concatenates role names and colors into span markup, while rawColumns renders the name column without output escaping. An administrator with role-creation or edit permission must store the payload, which then runs whenever another administrator opens the roles list.
