      <title>CVE-2026-92230 — Apache Karaf: Improper release of ClassLoader references via static ThreadLocal caching</title>
      <link>https://db.gcve.eu/vuln/cve-2026-92230</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Apache Software Foundation Apache Karaf&lt;/p&gt;
&lt;p&gt;Apache Karaf&amp;#39;s XmlUtils cached XML parser/transformer factories in static ThreadLocal fields on long-lived container threads. Because a ThreadLocal value outlives the OSGi bundle that created it, repeated bundle or feature install, update, or refresh operations can leave successive bundle ClassLoader&amp;#39;s pinned in memory and unreachable for garbage collection, leading to unbounded Metaspace growth and eventual denial of service of the Karaf instance.&lt;/p&gt;</description>
