RT is an open source, enterprise-grade issue and ticket tracking system. Versions 6.0.0 and above, prior to 6.0.3, contain a stored Cross-Site Scripting (XSS) vulnerability, where user-controlled data is rendered without proper HTML escaping. An authenticated user with permission to set the relevant data can inject JavaScript that executes when another RT user views the affected page. This issue has been fixed in version 6.0.3.

RT is an open source, enterprise-grade issue and ticket tracking system. Versions 6.0.0 and above, prior to 6.0.3 contain a reflected Cross-Site Scripting (XSS) vulnerability. An attacker who can induce an authenticated RT user to visit a crafted URL can execute arbitrary JavaScript in that user's browser session. There are no effective workarounds. Avoid following untrusted RT URLs. This issue has been fixed in version 6.0.3.
