vm2 package can allow unauthorized code execution

CVE-2026-47140 · published 3 days ago
Summary

The vm2 library used in Node.js applications—including those run through GitHub Actions and the @rootio version—has a security weakness that could let an attacker run unwanted code inside the sandbox, potentially affecting the host system or data. This matters because it may let a malicious user break out of the intended isolation. Install the latest patched version of vm2 that includes the fix.
