{"id":"CVE-2026-71322","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-71322","summary":"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.…","details":"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.","published":"2026-08-18T20:17:24.073","modified":"2026-08-18T20:17:24.073","cvss":{"score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/Netflix/lemur/commit/5683bbea8b10cce07f9a8abf1e4a7d3b2031c585","label":"Netflix/lemur@5683bbe"},"references":[{"type":"WEB","url":"https://github.com/Netflix/lemur/commit/5683bbea8b10cce07f9a8abf1e4a7d3b2031c585"},{"type":"WEB","url":"https://github.com/Netflix/lemur/releases/tag/v1.9.3"},{"type":"WEB","url":"https://github.com/Netflix/lemur/security/advisories/GHSA-4h97-p9wq-chqj"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-18T20:17:24.073"}}
