What is CVE-2026-92939?

The vulnerability in vm2 versions 3.11.3 through 3.11.6 allows the Node.js crypto module to be exposed to a NodeVM sandbox. When the crypto builtin is enabled, it can be exploited by executing commands that lead to a sandbox escape, permitting an attacker to use crypto.setEngine() with a custom native library. This library can be loaded using OpenSSL's dynamic loader, enabling potential execution of malicious code within the host environment. The issue is resolved in version 3.11.7.
