How to fix?

Upgrade Chainguard clusterctl to version 1.7.3-r1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream clusterctl package and not the clusterctl package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

The net/http HTTP/1.1 client mishandled the case where a server responds to a request with an "Expect: 100-continue" header with a non-informational (200 or higher) status. This mishandling could leave a client connection in an invalid state, where the next request sent on the connection will fail. An attacker sending a request to a net/http/httputil.ReverseProxy proxy can exploit this mishandling to cause a denial of service by sending "Expect: 100-continue" requests which elicit a non-informational response from the backend. Each such request leaves the proxy with an invalid connection, and causes one subsequent request using that connection to fail.
