Description
Dendrite team reports:
Events retrieved from a remote homeserver using /get_missing_events did
not have their signatures verified correctly. This could potentially allow
a remote homeserver to provide invalid/modified events to Dendrite via this
endpoint.
Note that this does not apply to events retrieved through other endpoints
(e.g. /event, /state) as they have been correctly verified.
Homeservers that have federation disabled are not vulnerable.
