Does this affect you?

It affects jahlives openssl_encrypt. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

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.
