## Overview

Jivejdon through 5.0 contains a stored cross-site scripting vulnerability that allows authenticated attackers to execute JavaScript by uploading attachments with an attacker-supplied Content-Type. Attackers can upload a file declared as text/html, which UploadShowAction serves inline, and share its link to run JavaScript on the application's origin for viewing users.
