CVE-2025-22142
In affected versions an admin can add the ability to have users fill out an additional field and users can inject javascript code into it that would be activated once a staffer visits the user's profile on staff panel.
Does this matter?
Lower severity and a low EPSS score (0.28%). Track it; it rarely justifies an emergency change on its own.
