      <title>CVE-2026-92933 — vm2 before 3.11.8 Information Disclosure via util.getCallSites</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-92933</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; patriksimek vm2&lt;/p&gt;
&lt;p&gt;vm2 is a sandbox for running untrusted Node.js code. In versions &amp;lt;= 3.11.7, NodeVM exposes the host `util` module to the sandbox as an unfiltered shallow copy (`Object.assign({}, util)` in `defaultBuiltinLoaderUtil`), and the deprecated `sys` builtin (an alias of host `util`) is exposed through the generic builtin loader. On Node.js &amp;gt;= 22.9 this hands sandboxed code `util.getCallSites()`, a programmatic stack-introspection API that returns the host process&amp;#39;s full call stack, including absolute file paths, function names, and line numbers for vm2 bridge internals and the embedding application&amp;#39;s entrypoint. This bypasses the host-frame redaction introduced for GHSA-v27g-jcqj-v8rw, which only applies to the `Error.prepareStackTrace` formatting channel. The issue is fixed in vm2 3.11.8.&lt;/p&gt;</description>
