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."}], "lastModified": "2026-04-24T17:11:49.060", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:nimiq:nimiq_proof-of-stake:*:*:*:*:*:rust:*:*", "vulnerable": true, "matchCriteriaId": "CD0CAAD1-7626-4A4A-A6F8-9DC46FE50731", "versionEndExcluding": "1.3.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
