Low risk27th percentile - higher than 27% of all known CVEs
Summary
Stored XSS vulnerability in CtrlPanel billing software (versions 1.1.1 and earlier) exists in ticket reply notifications. Unsanitized reply content is stored in the database and rendered unescaped via Blade's {!! !!} syntax, allowing arbitrary JavaScript execution in the victim's session context. Affects both admin and user notifications.
Risk Assessment
A low-privileged attacker can hijack admin sessions, steal credentials, or escalate privileges. The reverse path allows a malicious admin to attack regular users.
Recommendation
Upgrade CtrlPanel to version 1.2.0, which contains the fix.

See all- CVE-2026-34234Critical
CtrlPanel is open-source billing software for hosting providers. In versions 1.1.1 and prior, the web-based installer (public/installer/index.php) is vulnerable to unauthenticated Remote Code Execution (RCE) because it performs the install.lock check only after including and executing form handler files, leaving installer endpoints reachable on already-installed instances. The handlers also pass unsanitized user input directly into shell commands, allowing an attacker to submit crafted requests that execute arbitrary commands on the server. The vulnerability stems from two combined weaknesses: (1) premature form handler execution before the lock file gate, and (2) unsafe use of user input in shell command construction. This issue is reported to be actively exploited in the wild. The issue has been fixed in version 1.2.0.
- CVE-2026-34358High
CtrlPanel 1.1.1 and prior contains a broken access control vulnerability where admin controllers enforce permission checks on form display methods but omit them on corresponding write methods (store/update), allowing any authenticated user to bypass RBAC via direct POST/PATCH requests.
- CVE-2026-34246Medium
CtrlPanel (open-source billing software for hosting providers) versions 1.1.1 and prior contain a stored XSS vulnerability in the admin role management interface. The datatable() method in RoleController.php interpolates role name and color directly into HTML without sanitization, and .rawColumns(['actions', 'name']) disables automatic escaping. An admin with role creation or edit permissions can inject malicious code that executes on every load of the /admin/roles page by any admin.
- CVE-2026-34233Medium
CtrlPanel open-source billing software for hosting providers, versions 1.1.1 and prior, exposes multiple admin DataTable endpoints without authorization checks, allowing any authenticated user to access sensitive administrative data.
- CVE-2026-34216Medium
CtrlPanel versions up to 1.1.1 contain a remote code execution (RCE) vulnerability in the admin settings update endpoint. The vulnerability is due to missing validation of the loaded class, allowing an authenticated admin to dynamically call any class available in the Composer autoloader, potentially leading to code execution.
Original NVD description (English source)
CtrlPanel is open-source billing software for hosting providers. Versions 1.1.1 and prior contain a Stored Cross-Site Scripting (XSS) vulnerability in the ticket reply notification system. Unsanitized reply content ($newmessage) is stored directly in database notification payloads and later rendered unescaped via Blade's {!! !!} syntax in the recipient's browser. The flaw exists in both App\Notifications\Ticket\Admin\AdminReplyNotification (triggered when a user replies, targeting admins) and App\Notifications\Ticket\User\ReplyNotification (triggered when an admin replies, targeting users), allowing arbitrary JavaScript execution in the victim's session context. A low-privileged attacker can exploit this to hijack admin sessions, harvest credentials via fake login prompts or keyloggers, and escalate privileges by performing administrative actions on the victim's behalf. The reverse path also enables a malicious or compromised admin to target regular users in the same manner. This issue has been fixed in version 1.2.0.
