MEDIUM 4.9EPSS 1.31%
Does this matter?
Lower severity and a low EPSS score (1.31%). Track it; it rarely justifies an emergency change on its own.

A Keycloak cluster with multiple nodes could mishandle an expired session replacement and lead to an infinite loop. A malicious authenticated user could use this flaw to achieve Denial of Service on the server.
