CVE-2021-27673
Cross Site Scripting (XSS) in the "admin_boxes.ajax.php" component of Tribal Systems Zenario CMS v8.8.52729 allows remote attackers to execute arbitrary code by injecting arbitrary HTML into the "cID" parameter when creating a new HTML component.
Does this matter?
Lower severity and a low EPSS score (1.09%). Track it; it rarely justifies an emergency change on its own.
