Prior to version 1.3.0, an 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. Hashing an election macro header hashes `validators` and reaches `Validators::voting_keys()`, which calls `validator.voting_key.uncompress().unwrap()` and panics on invalid bytes. The patch for this vulnerability is included as part of v1.3.0. No known workarounds are available.","state":0,"publishedAt":"2026-04-22T20:16:41.077+00:00","modifiedAt":"2026-06-17T10:38:30.497+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/nimiq/core-rs-albatross/commit/e10eaebcd7774e5da6d0ff5e88ed13503474f0ff","https://github.com/nimiq/core-rs-albatross/pull/3662","https://github.com/nimiq/core-rs-albatross/releases/tag/v1.3.0","https://github.com/nimiq/core-rs-albatross/security/advisories/GHSA-7c4j-2m43-2mgh"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-34065","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-252","CWE-755"],"productCriteria":["cpe:2.3:a:nimiq:nimiq_proof-of-stake:*:*:*:*:*:rust:*:*"],"sourceDates":{"published":"2026-04-22T20:16:41.077","lastModified":"2026-06-17T10:38:30.497"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
