CVE-2019-4173
IBM Cognos Controller 10.2.0, 10.2.1, 10.3.0, 10.3.1, and 10.4.0 could allow a remote attacker to obtain sensitive information, caused by a flaw in the HTTP OPTIONS method, aka Optionsbleed.
Does this matter?
Lower severity and a low EPSS score (1.78%). Track it; it rarely justifies an emergency change on its own.
