Overview
Affected versions of this package are vulnerable to Missing Authentication for Critical Function in the Group Replication process. An attacker can gain unauthorized access to the server, potentially leading to data disclosure, modification, or service disruption by sending crafted network traffic to the group communication ports from an adjacent network. This is only exploitable if Group Replication is enabled and group communication ports are accessible from untrusted adjacent networks.
