Pimcore Web2Print Tools Bundle adds tools for web-to-print use cases to Pimcore. Prior to 5.2.2 and 6.1.1, the application fails to enforce proper server-side authorization checks on the API endpoint responsible for managing "Favourite Output Channel Configurations." Testing revealed that an authenticated backend user without explicitely lacking permissions for this feature was still able to successfully invoke the endpoint and modify or retrieve these configurations. This vulnerability is fixed in 5.2.2 and 6.1.1.

GHSA-4wg4-p27p-5q2r — Pimcore Web2Print Tools Bundle "Favourite Output Channel Configuration" Missing Function Level Authorization

2026-10-16T16:05:28.563162+00:00

Affected: Packagist: pimcore/web2print-tools-bundle

### Summary The application fails to enforce proper server-side authorization checks on the API endpoint responsible for managing "Favourite Output Channel Configurations." Testing revealed that an authenticated backend user without explicitely lacking permissions for this feature was still able to successfully invoke the endpoint and modify or retrieve these configurations. This violates the principle of least privilege and constitutes a classic example of Broken Access Control (OWASP Top 10 A01:2021). Because authorization is not validated at the function level, any authenticated user can perform actions intended only for privileged roles, leading to horizontal or vertical privilege escalation.

### Detail The backend user without permission was still able to list, create, update "Favourite Output Channel Configuration" item

### Step to Reproduce the issue login as Admin (full permission) and clicked "Favourite Output Channel Configurations" Then, captured and saved the request: -List API -Create API
