CVE-2026-81718

8.7 highEPSS 0.2%

High (8.7). EPSS 0.2% chance of exploitation in the next 30 days.

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.
