{"id":"GHSA-264v-m8fm-76jm","summary":"nimiq-transaction: Panic via `HistoryTreeProof` length mismatch","details":"### Impact\n`HistoryTreeProof::verify` panics on a malformed proof where `history.len() != positions.len()` due to `assert_eq!(history.len(), positions.len())`. \n\nThe 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.\n\n### Patches\n[The patch for this vulnerability](https://github.com/nimiq/core-rs-albatross/commit/6ff0800e8e031363e787c827d8d033e5694e4e6a) is included as part of [v1.3.0](https://github.com/nimiq/core-rs-albatross/releases/tag/v1.3.0).\n\n### Workarounds\nNo known workarounds know.","aliases":["CVE-2026-34067"],"modified":"2026-05-05T15:59:34.424080Z","published":"2026-04-22T19:20:50Z","database_specific":{"cwe_ids":["CWE-617"],"severity":"LOW","github_reviewed":true,"github_reviewed_at":"2026-04-22T19:20:50Z","nvd_published_at":"2026-04-22T21:17:07Z"},"references":[{"type":"WEB","url":"https://github.com/nimiq/core-rs-albatross/security/advisories/GHSA-264v-m8fm-76jm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34067"},{"type":"WEB","url":"https://github.com/nimiq/core-rs-albatross/pull/3659"},{"type":"WEB","url":"https://github.com/nimiq/core-rs-albatross/commit/6ff0800e8e031363e787c827d8d033e5694e4e6a"},{"type":"PACKAGE","url":"https://github.com/nimiq/core-rs-albatross"},{"type":"WEB","url":"https://github.com/nimiq/core-rs-albatross/releases/tag/v1.3.0"}],"affected":[{"package":{"name":"nimiq-transaction","ecosystem":"crates.io","purl":"pkg:cargo/nimiq-transaction"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"0.2.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-264v-m8fm-76jm/GHSA-264v-m8fm-76jm.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L"}]}
