CVE-2020-19201
A Stored Cross-Site Scripting (XSS) vulnerability was found in status_filter_reload.php, a page in the pfSense software WebGUI, on Netgate pfSense version 2.4.4-p2 and earlier.
Does this matter?
Lower severity and a low EPSS score (3.45%). Track it; it rarely justifies an emergency change on its own.
