GHSA-QH9R-J7RP-4X2M

An early warning has been issued regarding a vulnerability in OpenChoreo cluster-gateway that could allow unauthenticated access to data-plane operations. Users of affected versions should take immediate action.

What happened

An early warning has been issued for a vulnerability in OpenChoreo cluster-gateway. The issue arises from the management APIs being served on the same network listener as data-plane agent connections. This configuration allows unauthenticated access to privileged data-plane operations. An attacker could potentially perform operations normally restricted to the OpenChoreo API server.

The vulnerability affects OpenChoreo versions less than 1.0.2 or versions 1.1.0 and above but less than 1.1.2. Users of these versions are advised to upgrade to a patched version to mitigate the risk.

What to do about it

Upgrade to OpenChoreo version 1.0.2, 1.1.2, or 1.2.0 to fix the issue.
Review your OpenChoreo deployment to ensure that no unauthorized operations have been performed.
Monitor your systems for any unusual activity that may indicate an attempted exploit of this vulnerability.
Consult the primary sources for the latest information and updates on this vulnerability.
