When merged with the randomly generated 32-byte key using mergeKeys (16 bytes from each), the last 16 bytes are always \"arfoobarfoobarfo\". This enables an attacker with physical access to the EVE-OS device to attempt to brute force the remaining 128 bits of key.\n\n### Patches\n\nFixed in 7.10 and  8.12.1-lts\n\n### Workarounds\n\nNone","affected":[{"package":{"name":"github.com/lf-edge/eve","ecosystem":"Go","purl":"pkg:golang/github.com/lf-edge/eve"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.0.0-20220310190112-c0c966dc31e2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/02/GHSA-g7vp-j25f-h34p/GHSA-g7vp-j25f-h34p.json"}}],"references":[{"type":"WEB","url":"https://github.com/lf-edge/eve/security/advisories/GHSA-g7vp-j25f-h34p"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-43637"},{"type":"WEB","url":"https://github.com/lf-edge/eve/commit/c0c966dc31e2ed9aafc155e6be646adb14756c01"},{"type":"WEB","url":"https://asrg.io/security-advisories/cve-2023-43637"},{"type":"WEB","url":"https://asrg.io/security-advisories/vault-key-partially-predetermined"},{"type":"PACKAGE","url":"https://github.com/lf-edge/eve"}],"database_specific":{"cwe_ids":["CWE-321","CWE-798"],"github_reviewed":true,"github_reviewed_at":"2026-02-04T23:21:25Z","nvd_published_at":null,"severity":"MODERATE"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:P/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N"}]}
