Vulnerability details
The vulnerability allows a remote user to disclose sensitive information.
The vulnerability exists due to improper authorization in the legacy \"connections\" REST API endpoints when handling requests for connection data. A remote user can query the affected endpoints to disclose sensitive information.
The issue affects the `/api/dcim/console-connections/` and `/api/dcim/power-connections/` endpoints, and also `/api/dcim/interface-connections/` on the 2.4.x line only. Object-level permission constraints are silently ignored while model-level permission is still enforced.
