CVE-2018-1503
IBM WebSphere MQ 7.5, 8.0, and 9.0 could allow a remotely authenticated attacker to to send invalid or malformed headers that could cause messages to no longer be transmitted via the affected channel.
Does this matter?
Lower severity and a low EPSS score (1.99%). Track it; it rarely justifies an emergency change on its own.
