{"id":"CVE-2026-44505","state":"PUBLISHED","title":"Nimiq network-libp2p: Untrusted peer can wedge DHT","description":"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(&record.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.","publishedAt":"2026-06-09T23:44:20.580Z","updatedAt":"2026-06-10T16:32:27.475Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["nimiq core-rs-albatross"],"affected":[{"vendor":"nimiq","product":"core-rs-albatross","versions":[{"version":"< 1.4.0","status":"affected"}]}],"references":["https://github.com/nimiq/core-rs-albatross/security/advisories/GHSA-g39c-jcgg-qwvr","https://github.com/nimiq/core-rs-albatross/pull/3716","https://github.com/nimiq/core-rs-albatross/releases/tag/v1.4.0"],"weaknesses":["CWE-755"],"ingestedAt":"2026-10-29T20:11:57.932Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/44xxx/CVE-2026-44505.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-44505","state":"PUBLISHED","datePublished":"2026-06-09T23:44:20.580Z","dateUpdated":"2026-06-10T16:32:27.475Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-06T18:28:20.886Z"},"containers":{"cna":{"title":"Nimiq network-libp2p: Untrusted peer can wedge DHT","descriptions":[{"lang":"en","value":"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).
