CVE-2017-8802
Cross-site scripting (XSS) vulnerability in Zimbra Collaboration Suite (aka ZCS) before 8.8.0 Beta2 might allow remote attackers to inject arbitrary web script or HTML via vectors related to the "Show Snippet" functionality.
Does this matter?
Lower severity and a low EPSS score (1.27%). Track it; it rarely justifies an emergency change on its own.
