CVE-2026-34358 · Severity: high · CVSS 8.1 · Published 2026-05-19

CtrlPanel is an open-source billing and management platform used by hosting providers to manage customers, servers, and financial transactions. A security flaw allows any logged-in user to bypass administrative restrictions and perform sensitive actions, such as creating unlimited discount coupons, modifying user account balances, or changing their own account permissions. This could lead to significant financial loss, unauthorized access to customer data, and a total takeover of the hosting management system.

## Technical details

A broken access control vulnerability exists in CtrlPanel versions 1.1.1 and prior due to missing authorization checks in several administrative controllers. While the application correctly verifies permissions when displaying web forms (GET requests), it fails to perform equivalent checks on the corresponding 'store' and 'update' methods (POST/PATCH requests). An authenticated attacker can bypass Role-Based Access Control (RBAC) by sending direct HTTP requests to these endpoints. Affected components include controllers for coupons, vouchers, user accounts, and server management. Exploitation allows for privilege escalation, unauthorized modification of financial records, and manipulation of server ownership. The issue is resolved in version 1.2.0.
