Description
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.
