Severity: low · CVSS 2.3 · Published 2026-05-18

Sulu is a content management system used to build and manage websites. A security issue was found where the system's administrative interface could accidentally reveal sensitive API keys to logged-in users who have access to user management features. If a project uses these keys for custom functionality, an unauthorized user could potentially view them, leading to unauthorized access to connected services.

## Technical details

A vulnerability in the Sulu Security Bundle's UserController allows the exposure of the 'apiKey' field through the users endpoint controller. While Sulu's core does not use this field for its own authentication, custom project implementations that utilize this field for third-party integrations or custom logic may leak these keys to any authenticated user with access to the user management API. The issue stems from an improper access control (CWE-284) where the field descriptor is not correctly restricted in the API response. This has been patched in versions 2.6.23 and 3.0.6.
