CVE-2020-4590
IBM WebSphere Application Server Liberty 17.0.0.3 through 20.0.0.9 running oauth-2.0 or openidConnectServer-1.0 server features is vulnerable to a denial of service attack conducted by an authenticated client.
Does this matter?
Lower severity and a low EPSS score (1.24%). Track it; it rarely justifies an emergency change on its own.
