      <title>CVE-2026-95844 — Moquette deeply nested MQTT topics can cause stack exhaustion</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-95844</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; moquette-io moquette&lt;/p&gt;
&lt;p&gt;Moquette is a lightweight Java MQTT broker. Prior to 0.18.1, Moquette does not limit the depth of topic names and topic filters before processing them through recursive CTrie insertion and matching operations. A remote client can publish or subscribe with a deeply nested topic, causing a StackOverflowError that disrupts session processing and can deny service to broker clients. This issue is fixed in version 0.18.1.&lt;/p&gt;</description>
