{"id":"GHSA-7c4j-2m43-2mgh","summary":"nimiq-primitives: Node crash due to missing interlink validation in election macro block proposals","details":"### Impact\nAn untrusted p2p peer can cause a node to panic by announcing an election macro block whose `validators` set contains an invalid compressed BLS voting key.\n\nHashing an election macro header hashes `validators` and reaches `Validators::voting_keys()`, which calls `validator.voting_key.uncompress().unwrap()` and panics on invalid bytes.\n\n### Patches\n[The patch for this vulnerability](https://github.com/nimiq/core-rs-albatross/commit/e10eaebcd7774e5da6d0ff5e88ed13503474f0ff) 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.","aliases":["CVE-2026-34065"],"modified":"2026-05-05T16:03:26.628366Z","published":"2026-04-22T19:19:28Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-04-22T19:19:28Z","nvd_published_at":"2026-04-22T20:16:41Z","cwe_ids":["CWE-252","CWE-755"]},"references":[{"type":"WEB","url":"https://github.com/nimiq/core-rs-albatross/security/advisories/GHSA-7c4j-2m43-2mgh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34065"},{"type":"WEB","url":"https://github.com/nimiq/core-rs-albatross/pull/3662"},{"type":"WEB","url":"https://github.com/nimiq/core-rs-albatross/commit/e10eaebcd7774e5da6d0ff5e88ed13503474f0ff"},{"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-primitives","ecosystem":"crates.io","purl":"pkg:cargo/nimiq-primitives"},"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-7c4j-2m43-2mgh/GHSA-7c4j-2m43-2mgh.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
