CVE-2020-5934
On BIG-IP APM 15.1.0-15.1.0.5, 14.1.0-14.1.2.3, and 13.1.0-13.1.3.3, when multiple HTTP requests from the same client to configured SAML Single Logout (SLO) URL are passing through a TCP Keep-Alive connection, traffic to TMM can be disrupted.
Does this matter?
Lower severity and a low EPSS score (0.45%). Track it; it rarely justifies an emergency change on its own.
