Denial of service by the absence of restrictions on replies to posts in Discourse

Publisher and source text is retained separately from QFinch interpretation.

QFinch assessment

Discourse is an open source platform for community discussion. A user can create a post with many replies, and then attempt to fetch them all at once. This can potentially reduce the availability of a Discourse instance. This problem has been patched in the latest version of Discourse. All users area are advised to upgrade. There are no known workarounds for this vulnerability.
