Name of the Vulnerable Software and Affected Versions Discourse versions prior to the latest version

Description 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.

Recommendations Upgrade to the latest version of Discourse. As a temporary workaround, consider restricting the number of replies that can be fetched at once to minimize the risk of exploitation.
