CVE-2020-4828
IBM API Connect 10.0.0.0 through 10.0.1.0 and 2018.4.1.0 through 2018.4.1.13 is vulnerable to web cache poisoning, caused by improper input validation by modifying HTTP request headers.
Does this matter?
Lower severity and a low EPSS score (0.81%). Track it; it rarely justifies an emergency change on its own.
