Overview

CVE-2026-74870 is a low-severity vulnerability. It was published on August 17, 2026 and has a CVSS 3.1 base score of 3.3 (LOW).

This vulnerability has a CVSS 3.1 base score of 3.3, rated LOW. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

openssl_encrypt (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 (crypt_cli.py, handle_hsm_command). 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
