USBDriveCreator._verify_integrity_file only validates files listed in the manifest, so files added to the drive — including a root-level autorun payload — are not detected and integrity verification still passes. Additionally, a globally constant, source-embedded KDF salt (_LEGACY_FIXED_SALT) is used to derive the drive encryption key for any drive lacking a per-drive salt file, defeating precomputation resistance and enabling an offline rainbow-table attack.","published":"2026-08-27T17:21:02.033","modified":"2026-08-27T17:21:02.033","cvss":{"score":3.5,"severity":"LOW","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/jahlives/openssl_encrypt/security/advisories/GHSA-8jx3-27qf-3p97"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openssl-encrypt-before-1.4.9-integrity-bypass-via-added-files"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-27T17:21:02.033"}}
