Summary
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.
Risk Assessment
An authenticated attacker with admin privileges can remotely execute arbitrary code on the server, potentially leading to full system compromise.
Recommendation
Upgrade CtrlPanel to version 1.2.0 or later, which includes a 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-2026-34241High
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.
Original NVD description (English source)
CtrlPanel is open-source billing software for hosting providers. In versions 1.1.1 and prior, the admin settings update endpoint accepted a fully qualified class name directly from user-supplied request input and used it for dynamic static method calls and object instantiation without any allowlist validation, allowing for authenticated Remote Code Execution. An authenticated admin-level user could supply an arbitrary class name available in the Composer autoloader, potentially triggering unintended constructor or magic method execution. The update() method reads settings_class directly from the HTTP request and passed it to new $settings_class() and $settings_class::getValidations() without verifying that the provided value corresponds to a legitimate settings class: Because PHP resolves class names against the Composer autoloader at runtime, any autoloadable class in the application or its dependencies could be instantiated. Depending on the classes available in the dependency tree, this can trigger unintended side effects through constructors or magic methods (__construct, __toString, __wakeup), following a PHP object injection / gadget chain pattern. This issue has been fixed in version 1.2.0.
