CVE ID :CVE-2026-81718
Published : Aug. 27, 2026, 5:21 p.m. | 48 minutes ago
Description :openssl_encrypt versions before 1.4.9 use under-parameterized PBKDF2-HMAC-SHA256 with only 100,000 iterations to protect PQC keyfile private keys and 10,000 iterations for dual-encryption file-password verification. Attackers who obtain keyfiles or encrypted files can brute-force wrapping passwords offline using GPU or ASIC acceleration.
Severity: 8.7 | HIGH
