Summary

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.

This issue has been fixed in versions 5.0.10 and 6.0.3.
