{"cve":"CVE-2026-71322","nvd":{"published":"2026-08-18T20:17:24.073","modified":"2026-10-22T22:10:00.250","status":"Deferred","description":"Lemur manages TLS certificate creation. Prior to 1.9.3, CertificateExport placed its CertificatePermission ownership check inside the plugin.requires_key branch for POST /api/1/certificates//export. A plugin declaring requires_key false bypassed that check, and the handler still passed cert.private_key as an argument and recorded a key_view audit event. The bundled JavaTruststoreExportPlugin ignored the key, so the immediate exposure was limited to public certificate material and misleading audit entries, but a future plugin could have consumed the supplied key. The fix passes no private key to plugins that do not require one and confines ownership checks and key_view logging to actual private-key exports. This issue is fixed in version 1.9.3.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-862"],"references":["https://github.com/Netflix/lemur/commit/5683bbea8b10cce07f9a8abf1e4a7d3b2031c585","https://github.com/Netflix/lemur/releases/tag/v1.9.3","https://github.com/Netflix/lemur/security/advisories/GHSA-4h97-p9wq-chqj"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:26.291718493+00:00"},"epss":{"cve":"CVE-2026-71322","score":0.00234,"percentile":0.14109,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-4h97-p9wq-chqj","url":"https://osv.dev/vulnerability/GHSA-4h97-p9wq-chqj","summary":"Lemur: Missing authorization check on POST /certificates/<id>/export for plugins with requires_key = False","modified":"2026-08-19T12:55:59.250888945Z","packages":[{"ecosystem":"PyPI","name":"lemur","purl":"pkg:pypi/lemur","ranges":["<1.9.3"],"fixed":["1.9.3"]}]},{"id":"PYSEC-2026-3673","url":"https://osv.dev/vulnerability/PYSEC-2026-3673","summary":"Lemur: Missing authorization check on POST /certificates/<id>/export for plugins with requires_key = False","modified":"2026-08-19T12:45:05.612125709Z","packages":[{"ecosystem":"PyPI","name":"lemur","purl":"pkg:pypi/lemur","ranges":["<1.9.3"],"fixed":["1.9.3"]}]}],"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).
