Upgrade vm2 to version 3.12.1 or higher.
Overview
vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules.
Affected versions of this package are vulnerable to Improper Control of Dynamically-Managed Code Resources via the NodeVM builtin module denylist in lib/builtin.js, which omits child_process from DANGEROUS_BUILTINS. When a sandbox is configured with require: { builtin: ['*'] }, ['*', '-fs'], or an explicit ['child_process'] allowance (including node:child_process spellings), the real host child_process module is passed through to sandboxed code. A single execSync call then achieves arbitrary command execution on the host, constituting a full sandbox escape to remote code execution.
