CVE-2018-18668
GNUBOARD5 before 5.3.2.0 has XSS that allows remote attackers to inject arbitrary web script or HTML via the "homepage title" parameter, aka the adm/config_form_update.php cf_title parameter.
Does this matter?
Lower severity and a low EPSS score (1.44%). Track it; it rarely justifies an emergency change on its own.
