SCA: security update for lemur (GHSA-vr7c-r5gj-j3w5)

medium Tenable Cloud Security Plugin ID 441417

Description

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

 - Lemur manages TLS certificate creation. Prior to 1.9.0, when LDAP TLS is enabled (LDAP_USE_TLS = True),
 Lemur's LDAP authentication module unconditionally disables TLS certificate verification at the global
 ldap module level. This allows a man-in-the-middle attacker positioned between Lemur and the LDAP server
 to intercept all authentication credentials. This vulnerability is fixed in 1.9.0. (CVE-2026-44305)

Solution

Update the lemur library and its related packages to version 1.9.0 or later.
