      <title>CVE-2026-33216 — NATS has MQTT plaintext password disclosure</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-33216</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; nats-io nats-server, Red Hat Multicluster Global Hub 1.4.5, Red Hat Multicluster Global Hub 1.6.5, Red Hat multicluster global hub 1.5.3, Red Hat OpenShift Container Platform 4&lt;/p&gt;
&lt;p&gt;NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. Prior to versions 2.11.15 and 2.12.6, for MQTT deployments using usercodes/passwords: MQTT passwords are incorrectly classified as a non-authenticating identity statement (JWT) and exposed via monitoring endpoints. Versions 2.11.14 and 2.12.6 contain a fix. As a workaround, ensure monitoring end-points are adequately secured. Best practice remains to not expose the monitoring endpoint to the Internet or other untrusted network users.&lt;/p&gt;</description>
