Does this matter?

Lower severity and a low EPSS score (0.59%). Track it; it rarely justifies an emergency change on its own.

Description

An XSS issue was discovered in MDaemon Email Server version 25.0.1 and below. An attacker can send a specially crafted HTML e-mail message with JavaScript in an img tag. This could allow a remote attacker to load arbitrary JavaScript code in the context of a webmail user's browser window, and access user data.
