Lemur manages TLS certificate creation.

Published Aug 18, 2026CWE-862EPSS 0.23%

Overview

CVE-2026-71322 is a medium-severity vulnerability. It was published on August 18, 2026 and has a CVSS 3.1 base score of 4.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.3, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical 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.
