Summary
banq Jivejdon through 5.0 contains a stored cross-site scripting flaw (CWE-79) in attachment uploads. The application accepts an attacker-supplied Content-Type, so a file declared as text/html is served inline. An authenticated attacker uploads such a file and shares its link, so JavaScript runs on the application's origin for users who view it.
