CVE-2017-7631
Cross-site scripting (XSS) vulnerability in the share link function of File Station of QNAP 4.2.6 build 20171026, QTS 4.3.3 build 20170727 and earlier allows remote attackers to inject arbitrary web script or HTML.
Does this matter?
Lower severity and a low EPSS score (0.76%). Track it; it rarely justifies an emergency change on its own.
