CVE-2021-27909
For Mautic versions prior to 3.3.4/4.0.0, there is an XSS vulnerability on Mautic's password reset page where a vulnerable parameter, "bundle," in the URL could allow an attacker to execute Javascript code.
Does this matter?
Lower severity and a low EPSS score (4.07%). Track it; it rarely justifies an emergency change on its own.
