Versiant LYNX Customer Service Portal (CSP), version 3.5.2, is vulnerable to stored cross-site scripting, which could allow a local, authenticated attacker to insert malicious JavaScript that is stored and displayed to the end user.
Does this matter?
Lower severity and a low EPSS score (0.51%). Track it; it rarely justifies an emergency change on its own.
