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 Remote Code Execution (RCE) such that the Promise handler sanitization can be bypassed, allowing attackers to escape the sandbox.

Note:

According to the maintainer, the security issue cannot be properly addressed and the library will be discontinued.
