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.","state":0,"publishedAt":"2026-04-22T21:17:07.76+00:00","modifiedAt":"2026-10-26T22:10:00.163+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L","score":3.1,"severity":"LOW"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/nimiq/core-rs-albatross/commit/6ff0800e8e031363e787c827d8d033e5694e4e6a","https://github.com/nimiq/core-rs-albatross/pull/3659","https://github.com/nimiq/core-rs-albatross/releases/tag/v1.3.0","https://github.com/nimiq/core-rs-albatross/security/advisories/GHSA-264v-m8fm-76jm"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-34067","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-617"],"productCriteria":["cpe:2.3:a:nimiq:nimiq_proof-of-stake:*:*:*:*:*:rust:*:*"],"sourceDates":{"published":"2026-04-22T21:17:07.760","lastModified":"2026-10-26T22:10:00.163"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
