CVE-2018-10912
keycloak before version 4.0.0.final is vulnerable to a infinite loop in session replacement.
Does this matter?
Lower severity and a low EPSS score (1.31%). Track it; it rarely justifies an emergency change on its own.
Description
keycloak before version 4.0.0.final is vulnerable to a infinite loop in session replacement. 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.
