Synapse is a Matrix reference homeserver written in python (pypi package matrix-synapse). Matrix is an ecosystem for open federated Instant Messaging and VoIP. In Synapse before version 1.25.0, requests to user provided domains were not restricted to external IP addresses when calculating the key validity for third-party invite events and sending push notifications. This could cause Synapse to make requests to internal infrastructure. The type of request was not controlled by the user, although limited modification of request bodies was possible. For the most thorough protection server administrators should remove the deprecated
federation_ip_range_blacklistfrom their settings after upgrading to Synapse v1.25.0 which will result in Synapse using the improved default IP address restrictions. See the newip_range_blacklistandip_range_whitelistsettings if more specific control is necessary. - References
