Prior to version 1.3.0, `HistoryTreeProof::verify` panics on a malformed proof where `history.len() != positions.len()` due to `assert_eq!(history.len(), positions.len())`. The proof object is derived from untrusted p2p responses (`ResponseTransactionsProof.proof`) and is therefore attacker-controlled at the network boundary until validated. A malicious peer could trigger a crash by returning a crafted inclusion proof with a length mismatch. The patch for this vulnerability is included as part of v1.3.0. No known workarounds are available."}], "lastModified": "2026-04-24T17:12:48.173", "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"}
