SCA: security update for lemur (GHSA-4h97-p9wq-chqj)

medium Tenable Cloud Security Plugin ID 446093

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-71322)

Solution

Update the lemur library and its related packages to version 1.9.3 or later.
