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":"2026-04-22T19:52:43.916+00:00","modifiedAt":"2026-04-23T14:17:59.735+00:00","affected":[{"ecosystem":"Vendor product","name":"nimiq-transaction","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"nimiq\",\n                    \"product\": \"nimiq-transaction\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.3.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","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"}],"references":["https://github.com/nimiq/core-rs-albatross/security/advisories/GHSA-264v-m8fm-76jm","https://github.com/nimiq/core-rs-albatross/pull/3659","https://github.com/nimiq/core-rs-albatross/commit/6ff0800e8e031363e787c827d8d033e5694e4e6a","https://github.com/nimiq/core-rs-albatross/releases/tag/v1.3.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-34067","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-34067","identifiers":["CVE-2026-34067"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
