Summary
openssl_encrypt before 1.4.8 Hardware Pepper Information Disclosure
Details

opensslencrypt (pip) versions <= 1.4.7 contain an information exposure vulnerability where the 'hsm fido2-test' and 'hsm onlykey-test' diagnostic commands unconditionally print the full derived hardware pepper as hex to stdout/stderr (cryptcli.py, handlehsmcommand). The printed value can persist in terminal scrollback, session recordings, or CI logs. Impact is limited because the pepper is derived from a random per-invocation test salt and is salt-bound, so the leaked value cannot be used to decrypt real files. A related plugin issue logged raw prf_data outside the secret-redaction path. Fixed in 1.4.8 (and 1.5.0) by removing the hex dumps and routing plugin debug output through the redaction layer.
