CVE-2026-47137
Description
A flaw was found in vm2, an open-source virtual machine (VM) sandbox for Node.js. A remote attacker could bypass a security check designed to prevent the combination of nested environments and disabled module loading. This bypass occurs because a strict equality check for the require option can be circumvented by simply omitting the option, leading to an unintended configuration. Successful exploitation of this vulnerability could allow an attacker to escape the sandbox and achieve arbitrary code execution on the host system.
Statement
The Red Hat Product Security team has rated the impact of this vulnerability as Moderate in Red Hat Developer Hub and Ansible Automation Platform.The affected package is present in both products as a transitive dependency; however, the vulnerable sandbox functionality is not invoked in any production code path. The active sandboxing mechanism used by both products does not rely on this package, and user-supplied input cannot reach the vulnerable code under a standard deployment. Exploitation would require an attacker to independently route arbitrary JavaScript into the sandbox runtime, a condition not present in the default configuration of either product.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
