How to Fix CVE-2022-25893

To remediate this vulnerability, upgrade all affected Vm2 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

vm2 fixed: 3.9.10 
npm install vm2@3.9.10
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls vm2

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-25893, inspect your project dependencies using npm:

npm ls vm2

Analyze the terminal output to locate any version of Vm2 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.9.10), your application is affected.

Note: The npm ls vm2 command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Vm2, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The package vm2 before 3.9.10 is vulnerable to Arbitrary Code Execution due to the usage of prototype lookup for the WeakMap.prototype.set method. Exploiting this vulnerability leads to access to a host object and a sandbox compromise.
