Pimcore's Admin Classic Bundle is Missing Function Level Authorization on "Predefined Properties" Listing

Impact

The API endpoint for listing Predefined Properties in the Pimcore platform lacks adequate server-side authorization checks. Predefined Properties are configurable metadata definitions (e.g., name, key, type, default value) used across documents, assets, and objects to standardize custom attributes and improve editorial workflows, as documented in Pimcore's official properties guide. Testing confirmed that an authenticated backend user without explicit permissions for property management could successfully call the endpoint and retrieve the complete list of these configurations.

Original source description

Summary

The API endpoint for listing Predefined Properties in the Pimcore platform lacks adequate server-side authorization checks. Predefined Properties are configurable metadata definitions (e.g., name, key, type, default value) used across documents, assets, and objects to standardize custom attributes and improve editorial workflows, as documented in Pimcore's official properties guide. Testing confirmed that an authenticated backend user without explicit permissions for property management could successfully call the endpoint and retrieve the complete list of these configurations. This exemplifies Broken Access Control (OWASP Top 10 A01:2021), enabling unauthorized access to administrative features and potentially violating role-based access controls inherent to Pimcore's multi-user environment.

Details

The backend user without permission was still able to list "Predefined Properties" item

Step to Reproduce the issue

login as Admin (full permission) and clicked "Predefined Properties" <img width="1493" height="862" alt="Screenshot 2025-12-10 at 10 11 31 PM" src="https://github.com/user-attachments/assets/005d2704-347c-4aa1-b415-d52ab3794c99" />

Then, captured and saved the request:

Next, login a backend user with no permission <img width="1219" height="744" alt="Screenshot 2025-12-10 at 9 06 12 PM" src="https://github.com/user-attachments/assets/1dada4c4-d907-4477-9773-70dea3ef5816" />

After that, pasted the copied "Cookie" and "X-Pimcore-Csrf-Token" to captured request

Impact

Exploitation allows low-privileged users to enumerate all Predefined Properties, exposing internal metadata schemas, default values, and configuration details that may reveal business logic, data classification strategies, or sensitive defaults (e.g., proprietary keys or select options). In a PIM system like Pimcore, this could facilitate reconnaissance for further attacks, such as targeted data manipulation or privilege escalation, leading to unauthorized alterations of asset/object properties. For organizations handling regulated content (e.g., e-commerce catalogs under GDPR or PCI DSS), such exposure risks compliance breaches, intellectual property leakage, and operational inconsistencies from unintended property overrides.
