RTIR extends RT's HTML scrubber to allow an internal link placeholder, and the extension lets through any link that merely contains the placeholder, including links using the executable javascript: scheme. The change applies to the whole RT instance once RTIR is installed, not only to RTIR's own queues. Anyone who can add HTML content to a ticket on such an instance can store such a link. That includes an unauthenticated sender of HTML email to the Incident Reports queue, which RTIR opens to everyone by default. Script runs when a user clicks the link, in that user's session, and can act in RT with that user's authority.
