Discourse is an open source platform for community discussion. The issue allows new chat messages to be read by making an unauthenticated POST request to `MessageBus`. There are no known workarounds for this issue. Users are advised to upgrade to a patched version.
**Recommendations**
For versions prior to 3.1.1 stable, upgrade to version 3.1.1 stable or later.

As a temporary workaround, consider restricting access to the `MessageBus` until a patch is applied.
