RT is an open source, enterprise-grade issue and ticket tracking system. Versions 5.0.0 and 6.0.0 and above, prior to both 5.0.10 and 6.0.3 contain a Cross-Site Scripting (XSS) vulnerability where uploaded content is served inline rather than as an attachment. An authenticated user who can upload content can include JavaScript in the upload that will execute in the browser session of any RT user who later views or downloads it. This issue has been fixed in versions 5.0.10 and 6.0.3.
