Behoben in
3.11.1
CVE-2026-44007 is a remote code execution (RCE) vulnerability affecting the vm2 Node.js sandbox library. This flaw arises when nesting is enabled (nesting: true) within a NodeVM, allowing untrusted code to bypass restrictions and execute arbitrary operating system commands on the host system. The vulnerability impacts versions 0.0.0 up to and including 3.10.x, and a fix is available in version 3.11.1.
Auswirkungen und Angriffsszenarien
The impact of CVE-2026-44007 is severe. An attacker who can inject code into a sandboxed environment with nesting enabled can completely compromise the host system. This allows for arbitrary code execution, potentially leading to data theft, system takeover, and further lateral movement within the network. The vulnerability bypasses the intended security of the vm2 sandbox, rendering it ineffective against malicious code. This resembles the impact of other sandbox escape vulnerabilities where the isolation boundary is breached, granting attackers full control.
Ausnutzungskontext
CVE-2026-44007 was published on May 13, 2026. Its severity is rated as CRITICAL (CVSS 9.1). Public proof-of-concept (POC) code is likely to emerge given the ease of exploitation and the high impact. The vulnerability's nature makes it a potential candidate for inclusion on the CISA Known Exploited Vulnerabilities (KEV) catalog and may receive an EPSS score indicating a high probability of exploitation. Monitor security advisories and threat intelligence feeds for updates.

Mitigation und Workarounds
The primary mitigation for CVE-2026-44007 is to upgrade to vm2 version 3.11.1 or later. If upgrading is not immediately feasible due to compatibility issues or breaking changes, consider disabling nesting (setting nesting: false) within your NodeVM configurations. This will significantly reduce the attack surface, although it may impact the functionality of your application. As a temporary workaround, implement strict input validation and sanitization on any data passed to the sandboxed environment to minimize the risk of code injection. Monitor your systems for suspicious activity, particularly processes spawned from within the Node.js environment.

Häufig gestellte Fragen
What is CVE-2026-44007 — RCE in vm2 Node.js Sandbox?
CVE-2026-44007 is a critical remote code execution vulnerability in the vm2 Node.js sandbox library. It allows attackers to execute arbitrary code on the host system if nesting is enabled within the sandbox, impacting versions 0.0.0 through 3.11.0.
Am I affected by CVE-2026-44007 in vm2 Node.js Sandbox?
You are likely affected if you are using vm2 versions 0.0.0 to 3.11.0 and have nesting enabled (nesting: true) in your NodeVM configurations. Carefully review your application's dependencies and configurations.
How do I fix CVE-2026-44007 in vm2 Node.js Sandbox?
Upgrade to vm2 version 3.11.1 or later. If immediate upgrade is not possible, disable nesting (nesting: false) as a temporary mitigation. Implement strict input validation and monitor your systems for suspicious activity.
Is CVE-2026-44007 being actively exploited?
While no active exploitation has been publicly confirmed, the vulnerability's severity and ease of exploitation suggest it is likely to be targeted. Monitor security advisories and threat intelligence feeds for updates.
