Summary
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.
Risk Assessment
An attacker without admin privileges can issue API credentials, generate unlimited coupons and vouchers, alter shop pricing, reassign server ownership, and modify user accounts (including roles, passwords, and Pterodactyl IDs), leading to full privilege escalation.
Recommendation
Immediately upgrade CtrlPanel to version 1.2.0, which fixes this vulnerability.

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-2026-34246Medium
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-2026-34241High
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.
- 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 contains a broken access control vulnerability where multiple admin controllers enforce permission checks on form display methods but omit equivalent checks on the corresponding write methods, allowing any authenticated user to bypass RBAC via direct POST/PATCH requests. Controllers missing checks on write methods store() and update() include ApplicationApiController (admin.api.write), CouponController (admin.coupons.write), PartnerController (admin.partners.write), ShopProductController (admin.store.write), UsefulLinkController (admin.useful_links.write), and VoucherController (admin.voucher.write); ProductController (admin.products.edit), ServerController (write/change_owner/change_identifier), and UserController (write/change_email/change_credits/change_username/change_password/change_role/change_referral/change_ptero/change_serverlimit) are missing checks on update() only, and ActivityLogController exposed empty stub store()/update() methods that silently accepted any request. An authenticated attacker without admin write privileges can issue API credentials, generate unlimited coupons and vouchers, assign arbitrary partner commission and discount rates, alter shop product pricing and limits, reassign server ownership or identifiers, and modify user accounts including roles, credits, passwords, and linked Pterodactyl IDs to achieve full privilege escalation, as well as abuse logBackIn() without the login_as permission to interfere with admin impersonation sessions. This issue has been fixed in version 1.2.0.
