Weakness in auth chain indexing allows DoS from remote room members through disk fill and high CPU usage. A remote Matrix user with malicious intent, sharing a room with Synapse instances before 1.104.1, can dispatch specially crafted events to exploit a weakness in how the auth chain cover index is calculated. This can induce high CPU consumption and accumulate excessive data in the database of such instances, resulting in a denial of service. Servers in private federations, or those that do not federate, are not affected. |
