MEDIUM 4.2EPSS 0.16%

Does this matter?

Lower severity and a low EPSS score (0.16%). Track it; it rarely justifies an emergency change on its own.

Description

The IRIS web application in version 2.4.26 and possibly others contains a logout functionality which is ineffective. Stolen session cookies can therefore be misused for a long time.
