How to Fix GHSA-7r5f-7qr4-pf6q

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

notevil fixed: 1.3.2 
npm install notevil@1.3.2
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 notevil

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-7r5f-7qr4-pf6q, inspect your project dependencies using npm:

npm ls notevil

Analyze the terminal output to locate any version of Notevil in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.3.2), your application is affected.

Note: The npm ls notevil 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 General Security Weakness. In Notevil, 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

Versions of `notevil` prior to 1.3.2 are vulnerable to Sandbox Escape leading to Remote Code Execution. The package fails to prevent access to the `Function` constructor by not checking the return values of function calls. This allows attackers to access the Function prototype's constructor leading to the Sandbox Escape. An example payload is: ``` var safeEval = require('notevil') var input = "" + "function fn() {};" + "var constructorProperty = Object.getOwnPropertyDescriptors(fn.__proto__).constructor;" + "var properties = Object.values(constructorProperty);" + "properties.pop();" + "properties.pop();" + "properties.pop();" + "var Function = properties.pop();" + "(Function('return this'))()"; safeEval(input)``` ## Recommendation Upgrade to version 1.3.2 or later.
