Official Description
vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, VM2 suffers from a sandbox breakout vulnerability. This allows attackers to write code which can escape from the VM2 sandbox and execute arbitrary commands on the host system. This issue has been patched in version 3.11.4.
Risk Analysis
This critical vulnerability in vm2, a Node.js sandbox, allows attackers to break out of the sandbox and execute arbitrary commands on the host system. This flaw enables full system compromise. With a CVSS score of 10.0, this issue is extremely severe and requires immediate attention.
No public exploit is currently known for this vulnerability. The flaw is remotely exploitable due to its network attack vector and low attack complexity.
Upgrade vm2 to version 3.11.4 or later. Ensure all Node.js applications utilizing vm2 are updated to the patched version.
Technical Analysis
CVE-2026-47208 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 10.0.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
