CVE-2026-34246

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.

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.

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.

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.

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.
