CVE-2020-4592
IBM MQ Appliance 9.1.CD and LTS could allow an authenticated user, under nondefault configuration to cause a data corruption attack due to an error when using segmented messages.
Does this matter?
Lower severity and a low EPSS score (0.79%). Track it; it rarely justifies an emergency change on its own.
