CVE-2020-25689
A memory leak flaw was found in WildFly in all versions up to 21.0.0.Final, where host-controller tries to reconnect in a loop, generating new connections which are not properly closed while not able to connect to domain-controller.
Does this matter?
Lower severity and a low EPSS score (1.49%). Track it; it rarely justifies an emergency change on its own.
