CVE ID :CVE-2026-81717
Published : Aug. 27, 2026, 5:21 p.m. | 1 hour, 8 minutes ago
Description :openssl_encrypt (pip package openssl-encrypt) before 1.4.9 contains two weaknesses in the portable USB drive feature, whose threat model treats the removable drive as untrusted (attacker with physical write access). 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.
Severity: 9.3 | CRITICAL
