CVE-2018-1551
IBM WebSphere MQ 8.0.0.2 through 8.0.0.8 and 9.0.0.0 through 9.0.0.3 could allow users to have more authority than they should have if an MQ administrator creates an invalid user group name.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.14%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
