CVE-2021-28088
Cross-site scripting (XSS) in modules/content/admin/content.php in ImpressCMS profile 1.4.2 allows remote attackers to inject arbitrary web script or HTML parameters through the "Display Name" field.
Does this matter?
Lower severity and a low EPSS score (0.87%). Track it; it rarely justifies an emergency change on its own.
