{"cve":"CVE-2026-74870","nvd":{"published":"2026-08-17T11:16:41.293","modified":"2026-09-03T16:07:10.300","status":"Analyzed","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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":3.3},"cwes":["CWE-532"],"references":["https://github.com/jahlives/openssl_encrypt/security/advisories/GHSA-p9g8-wvh4-2jmx","https://www.vulncheck.com/advisories/openssl-encrypt-before-hardware-pepper-information-disclosure"],"products":["jahlives:openssl_encrypt"],"source":"nvd","synced_at":"2026-10-19T22:49:10.689564601+00:00"},"epss":{"cve":"CVE-2026-74870","score":0.00261,"percentile":0.17895,"date":"2026-10-31"},"kev":null,"osv":[{"id":"PYSEC-2026-3956","url":"https://osv.dev/vulnerability/PYSEC-2026-3956","summary":"","modified":"2026-09-10T13:00:03.320612550Z","packages":[{"ecosystem":"PyPI","name":"openssl-encrypt","purl":"pkg:pypi/openssl-encrypt","ranges":["<1.4.7"],"fixed":["1.4.7"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
