nimiq-libp2p is a Nimiq network implementation based on libp2p. Prior to version 1.3.0, MessageCodec::read_request and read_response call read_to_end() on inbound substreams, so a remote peer can send only a partial frame and keep the substream open. because Behaviour::new also sets with_max_concurrent_streams(1000), the node exposes a much larger stalled-slot budget than the library default. The patch for this vulnerability is formally released as part of v1.3.0. No known workarounds are available.
