{"id":"CVE-2026-34065","summary":"nimiq-primitives: Node crash due to missing interlink validation in election macro block proposals","details":"nimiq-primitives contains primitives (e.g., block, account, transaction) to be used in Nimiq's Rust implementation. 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.","aliases":["GHSA-7c4j-2m43-2mgh"],"modified":"2026-07-15T01:49:20.794994295Z","published":"2026-04-22T19:45:01.171Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-252","CWE-755"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34065.json"},"references":[{"type":"WEB","url":"https://github.com/nimiq/core-rs-albatross/releases/tag/v1.3.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34065.json"},{"type":"ADVISORY","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":"FIX","url":"https://github.com/nimiq/core-rs-albatross/commit/e10eaebcd7774e5da6d0ff5e88ed13503474f0ff"},{"type":"FIX","url":"https://github.com/nimiq/core-rs-albatross/pull/3662"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nimiq/core-rs-albatross","events":[{"introduced":"0"},{"fixed":"5bd15d9af710abeecdfb63d0a721dc883efb59c4"},{"fixed":"e10eaebcd7774e5da6d0ff5e88ed13503474f0ff"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.3.0"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:nimiq:nimiq_proof-of-stake:*:*:*:*:*:rust:*:*"}}],"versions":["v1.2.2","v1.2.1","v1.2.0","v1.1.1","v1.1.0","v1.0.9","v1.0.8","v1.0.7","v1.0.6","v1.0.5","v1.0.4","v1.0.3","v1.0.2","v1.0.1","v1.0.0","v1.0.0-rc.5","v1.0.0-rc.4","v1.0.0-rc.3","v1.0.0-rc.2","v1.0.0-rc.1","v1.0.0-rc.0","v0.24.4","v0.24.3","v0.24.2","v0.24.1","v0.24.0","v0.23.0","v0.22.3","v0.22.2","v0.22.1","v0.22.0","v0.21.1","v0.21.0","v0.20.5","v0.20.4","v0.20.3","v0.20.2","v0.20.1","v0.20.0","v0.19.0","v0.18.0","v0.17.0","v0.16.1","v0.16.0","v0.15.0","v0.14.0","v0.13.1","v0.13.0","v0.12.1","v0.12.0","v0.11.5","v0.11.4","v0.11.3","v0.11.2","v0.11.1","v0.11.0","v0.10.0","v0.9.0","v0.8.3","v0.8.2","v0.8.1","v0.8.0","v0.7.0","v0.6.0","v0.5.4","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.1","v0.4.0","v0.3.3","v0.3.2","v0.3.1","v0.3.0","v0.2.2","v0.2.1","v0.2.0","v0.1.0","v0.1.0-rc.3","v0.1.0-rc.2","v0.1.0-rc.1","v0.1.0-rc.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-34065.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
