An authenticated user with upload permission to a hosted repository can store content that causes arbitrary JavaScript to execute in the browser of any user who browses that repository directory via the HTML index page in Sonatype Nexus Repository versions 3.6.0 through versions before 3.92.0. This could allow the attacker to perform actions in the context of the victim's session.
