What is CVE-2017-8445?

A vulnerability exists in the X-Pack Security TLS trust manager, affecting versions 5.0.0 to 5.5.1. In situations where trust material reloading fails, the TLS trust manager could be replaced by an instance that bypasses certificate validation, allowing any node with any certificate to connect to the cluster. This presents a significant risk as it undermines the intended security measures, which should involve rejecting untrusted certificates to maintain secure communications between nodes.
