Vulnerability details
The vulnerability allows a remote user to disclose sensitive information.
The vulnerability exists due to improper access control in GET /api/extclients/{network} and GET /api/nodes/{network} when handling requests for network configuration records. A remote user can send a crafted API request to disclose sensitive information.
