Discourse is an open-source discussion platform. Prior to version 3.1.1 of the stable branch, a malicious user can create an unlimited number of drafts with very long draft keys which may end up exhausting the resources on the server. The issue is patched in version 3.1.1 of the stable branch. There are no known workarounds.
