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. Synapse homeservers are affected by this issue if and only if they are joined to rooms which members of untrusted homeservers are joined or invited to. - Synapse homeservers in rooms available over public federation **are** affected. - Synapse homeservers with federation disabled are not affected. - Synapse homeservers in a closed federation containing only trusted servers are not affected. - Synapse homeservers which are only joined to rooms with federation disabled[^1] are not affected. ### Patches Administrators of homeservers with federation enabled are advised to upgrade to 1.68.0 or higher. ### Workarounds * Federati...
