Does this matter?
Lower severity and a low EPSS score (2.56%). Track it; it rarely justifies an emergency change on its own.
Description

An attacker could exploit this issue by tricking a user into following a specially crafted link, granting the attacker javascript execution in the context of the victim's browser.
