Synapse is an open-source Matrix homeserver written and maintained by the
Matrix.org Foundation. If Synapse and a malicious homeserver are both
joined to the same room, the malicious homeserver can trick Synapse into
accepting previously rejected events into its view of the current state of
that room. This can be exploited in a way that causes all further messages
and state changes sent in that room from the vulnerable homeserver to be
rejected. This issue has been patched in version 1.68.0
