vm2 is a sandbox that can run untrusted code with whitelisted Nodes built-in modules. Prior to version 3.9.15, vm2 was not properly handling host objects passed to Error.prepareStackTrace in case of unhandled async errors. A threat actor could bypass the sandbox protections to gain remote code execution rights on the host running the sandbox. This vulnerability was patched in the release of version 3.9.15 of vm2. There are no known workarounds.
Weakness
The product does not properly restrict reading from or writing to dynamically-managed code resources such as variables, objects, classes, attributes, functions, or executable instructions or statements.
