CVE-2024-45517
A Cross-Site Scripting (XSS) vulnerability in the /h/rest endpoint of the Zimbra webmail and admin panel interfaces allows attackers to execute arbitrary JavaScript in the victim's session.
Does this matter?
Lower severity and a low EPSS score (0.52%). Track it; it rarely justifies an emergency change on its own.
