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.","state":0,"publishedAt":"2026-04-22T19:20:50+00:00","modifiedAt":"2026-05-05T15:59:34.42408+00:00","affected":[{"ecosystem":"crates.io","name":"nimiq-transaction","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"last_affected","version":"0.2.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"LOW"}],"references":["https://github.com/nimiq/core-rs-albatross/security/advisories/GHSA-264v-m8fm-76jm","https://nvd.nist.gov/vuln/detail/CVE-2026-34067","https://github.com/nimiq/core-rs-albatross/pull/3659","https://github.com/nimiq/core-rs-albatross/commit/6ff0800e8e031363e787c827d8d033e5694e4e6a","https://github.com/nimiq/core-rs-albatross","https://github.com/nimiq/core-rs-albatross/releases/tag/v1.3.0"],"sourceUrl":"https://github.com/advisories/GHSA-264v-m8fm-76jm","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-264v-m8fm-76jm","identifiers":["GHSA-264v-m8fm-76jm","CVE-2026-34067"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
