  "details": "Nimiq is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. network-libp2p handles kad get-record query progress in handle_dht_get (network-libp2p/src/swarm.rs). Prior to version 1.4.0, when a peer returns a FoundRecord, the code verifies the record via dht_verifier.verify(\u0026record.record). On verifier error, handle_dht_get logs and returns early without completing the oneshot used by Network::dht_get, and without cleaning up per-query bookkeeping. Later query progress can hit the \"DHT inconsistent state\" path and also return without cleanup. Because Network::dht_get awaits the oneshot without a timeout, the caller future can hang indefinitely. This issue has been patched in version 1.4.0.",
