CVE-2025-46549
Prior to version 4.5.4, an attacker can use a reflected cross-site scripting attack to steal cookies from an authenticated user by having them click on a malicious link.
Does this matter?
Lower severity and a low EPSS score (0.53%). Track it; it rarely justifies an emergency change on its own.
