Discourse is an open source discussion platform. Prior to version 3.0.4 of the stable
branch, the lack of restrictions on the iFrame tag makes it easy for an attacker to exploit the vulnerability and hide subsequent comments from other users. This issue is patched in version 3.0.4 of the stable
branch. There are no known workarounds.
