| Package | Affected versions | Patched versions |
|---|---|---|
| openssl-encrypt | < 1.4.9 | 1.4.9 |
| openssl encrypt | < 1.4.9 | 1.4.9 |
openssl_encrypt versions before 1.4.9 derive the remote-pepper wrap key using unsalted HKDF-SHA256 or bare SHA-256 of the password, allowing identical keys across all users and files. Attackers with access to wrapped pepper blobs can precompute a single dictionary table and perform fleet-wide offline password guessing at hardware speed to recover user passwords.
