Does this matter?

Lower severity and a low EPSS score (0.25%). Track it; it rarely justifies an emergency change on its own.

Description

DigitalCanion has discovered a stored Cross-Site Scripting (XSS) vulnerability that allows an authenticated malicious user to inject persistent JavaScript or HTML content into the web application. The specific flaw exists within the web portal listening on TCP port 443, under Configuration → Domains, specifically in the “Description” field. The application fails to properly validate or sanitize user-supplied input before storing and subsequently rendering the field. By injecting malicious JavaScript into the Description field, an attacker can modify the content and behavior of the affected page when it is viewed by other users. This could allow an attacker to alter the page's appearance, display attacker-controlled content, or construct convincing phishing scenarios within the application's trusted web context.
