Does this matter?
Lower severity and a low EPSS score (3.03%). Track it; it rarely justifies an emergency change on its own.
Description
Exponent CMS 2.6.0patch2 allows an authenticated user to inject persistent JavaScript code on the "User-Agent" header when logging in. When an administrator user visits the "User Sessions" tab, the JavaScript will be triggered allowing an attacker to compromise the administrator session.
