The Single Sign-On (SSO) feature in F5 BIG-IP APM 11.x before 11.6.0 HF6 and BIG-IP Edge Gateway 11.0.0 through 11.3.0 might allow remote attackers to obtain sensitive SessionId information by leveraging access to the Location HTTP header in a redirect.

Does this matter?

Lower severity and a low EPSS score (1.53%). Track it; it rarely justifies an emergency change on its own.
