<p>46.0.6 - 2026-03-25</p>
<pre><code>
* **SECURITY ISSUE**: Fixed a bug where name constraints were not
applied
  to peer names during verification when the leaf certificate contains a
wildcard DNS SAN. Ordinary X.509 topologies are not affected by this
bug,
including those used by the Web PKI. Credit to **Oleh Konko (1seal)**
for
  reporting the issue. **CVE-2026-34073**
<p>.. _v46-0-5:<br />
