CVE-2022-4492 is a high-severity flaw (CVSS 7.5) affecting build of quarkus, integration camel for spring boot, integration camel k. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The undertow client is not checking the server identity presented by the server certificate in https connections. This is a compulsory step (at least it should be performed by default) in https and in http/2. I would add it to any TLS client protocol.
