synapse is an open source application developed by Matrix. A resource management error vulnerability exists in versions of Matrix synapse prior to 1.53.0. The vulnerability stems from Synapse generating URL previews of media streams without limiting the connection time, which could be exploited to make Synapse connect to a streaming server (e.g. Icecast) for long periods of time in some cases.
