CVE-2021-23052
On version 14.1.x before 14.1.4.4 and all versions of 13.1.x, an open redirect vulnerability exists on virtual servers enabled with a BIG-IP APM access policy.
Does this matter?
Lower severity and a low EPSS score (0.58%). Track it; it rarely justifies an emergency change on its own.
