3.6.11- Upgrade vm2 to this version or later
Description
This affects the package vm2 before 3.6.11. It is possible to trigger a RangeError exception from the host rather than the "sandboxed" context by reaching the stack call limit with an infinite recursion. The returned object is then used to reference the mainModule property of the host code running the script allowing it to spawn a child_process and execute arbitrary code.
Affected versions
npm
| Package | Vulnerable | Fixed in |
|---|---|---|
| vm2 | < 3.6.11 |
3.6.11 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
vm2 npm → 3.6.11
- npm
npm install vm2@3.6.11- yarn
yarn add vm2@3.6.11- pnpm
pnpm add vm2@3.6.11

Weakness
CWE-674: Uncontrolled Recursion
The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
How to prevent it
- Implementation: Ensure that an end condition will be reached under all logic conditions. The end condition may include checking against the depth of recursion and exiting with an error if the recursion goes too deep. The complexity of the end condition contributes to the effectiveness of this action.
- Implementation: Increase the stack size.
