In versions 1.2.2 and below, an unauthenticated p2p peer can cause the RequestMacroChain message handler task to panic. Sending a RequestMacroChain message where the first locator hash on the victim’s main chain is a micro block hash (not a macro block hash) causes said panic. The RequestMacroChain::handle handler selects the locator based only on \"is on main chain\", then calls get_macro_blocks() and panics via .unwrap() when the selected hash is not a macro block (BlockchainError::BlockIsNotMacro). This issue has been fixed in version 1.3.0.","state":0,"publishedAt":"2026-04-14T00:16:07.023+00:00","modifiedAt":"2026-10-26T21:10:00.17+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:L","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/nimiq/core-rs-albatross/commit/ae6c1e92342e72f80fd12accbe66ee80dd6802ac","https://github.com/nimiq/core-rs-albatross/pull/3660","https://github.com/nimiq/core-rs-albatross/releases/tag/v1.3.0","https://github.com/nimiq/core-rs-albatross/security/advisories/GHSA-48m6-486p-9j8p"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-34069","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-617"],"productCriteria":["cpe:2.3:a:nimiq:nimiq_proof-of-stake:*:*:*:*:*:rust:*:*"],"sourceDates":{"published":"2026-04-14T00:16:07.023","lastModified":"2026-10-26T21:10:00.170"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
