CVE-2020-35125
A cross-site scripting (XSS) vulnerability in the forms component of Mautic before 3.2.4 allows remote attackers to inject executable JavaScript via mautic[return] (a different attack method than CVE-2020-35124, but also related to the Referer concept).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.69%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
