CVE-2018-1943
IBM Cloud Private 3.1.0 and 3.1.1 is vulnerable to HTTP HOST header injection, caused by improper validation of input.
Does this matter?
Lower severity and a low EPSS score (1.03%). Track it; it rarely justifies an emergency change on its own.
Description
IBM Cloud Private 3.1.0 and 3.1.1 is vulnerable to HTTP HOST header injection, caused by improper validation of input.
