Pimcore is Vulnerable to Broken Access Control: Missing Function Level Authorization on "Static Routes" Listing

Moderate severity GitHub Reviewed Published Jan 15, 2026 in pimcore/pimcore • Updated Jan 15, 2026

Package

composer pimcore/pimcore (Composer)

>= 12.0.0-RC1, <= 12.3

Description

Summary

The application fails to enforce proper server-side authorization checks on the API endpoint responsible for reading or listing static routes. In Pimcore, static routes are custom URL patterns defined via the backend interface or the var/config/staticroutes.php file, including details like regex-based patterns, controllers, variables, and priorities. These routes are registered automatically through the PimcoreStaticRoutesBundle and integrated into the MVC routing system. Testing revealed that an authenticated backend user lacking explicit permissions was able to invoke the endpoint (e.g., GET /api/static-routes) and retrieve sensitive route configurations. This violates OWASP A01:2021 Broken Access Control, as function-level authorization is absent, allowing unauthorized access to internal routing metadata. Without validation, the endpoint exposes route structures, potentially revealing application architecture, endpoints, or custom logic intended for administrative roles only.

Details

The backend user without permission was still able to list "Static Routes" item

Step to Reproduce the issue

login as Admin (full permission) and clicked "Static Routes"
Screenshot 2025-12-10 at 9 36 04 PM
Then, captured and saved the request:
-List API
Screenshot 2025-12-10 at 9 44 17 PM

Next, login a backend user with no permission

The copy the "Cookie" and "X-Pimcore-Csrf-Token"
Screenshot 2025-12-10 at 9 10 47 PM

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

-List API

Impact

Exploitation enables low-privileged users to enumerate static routes, gaining reconnaissance into URL patterns, associated controllers, and parameter handling, which could facilitate targeted attacks like path traversal, injection via exposed variables, or discovery of hidden administrative paths. In a Pimcore environment, this might expose site-specific routing for multi-tenant setups, leading to unauthorized data access, workflow manipulation, or escalation to broader system compromise. Business impacts include intellectual property leakage of custom routing logic, regulatory non-compliance (e.g., GDPR for exposed configs), and increased attack surface for chaining with other vulnerabilities.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
