Vulnerability Description
MWDB Core versions >=2.2.0 and <2.19.0 contain a missing authorization vulnerability in the Remote Instances proxy API. The proxy API does not verify authentication for incoming requests, allowing an unauthenticated remote attacker to send arbitrary requests to a remote MWDB instance using the identity and permissions associated with the configured API key. This can result in unauthorized actions being performed on the remote instance as if executed by the user whose API key was used to set up the remote instance. The vulnerability is limited to deployments where Remote Instances have been configured.This issue has been fixed in version 2.19.0
