A stored cross-site scripting (XSS) vulnerability was discovered in pfSense 2.4.5-p1 which allows an authenticated attacker to execute arbitrary web scripts via exploitation of the load_balancer_monitor.php function.
Does this matter?
Lower severity and a low EPSS score (5.31%). Track it; it rarely justifies an emergency change on its own.
