How to Fix CVE-2022-25904

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

safe-eval fixed: Latest secure release 
npm install safe-eval@Latest secure release
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 safe-eval

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-25904, inspect your project dependencies using npm:

npm ls safe-eval

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

Note: The npm ls safe-eval 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-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution'), where the product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype. In Safe eval, 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

All versions of package safe-eval are vulnerable to Prototype Pollution which allows an attacker to add or modify properties of the Object.prototype.Consolidate when using the function safeEval. This is because the function uses vm variable, leading an attacker to modify properties of the Object.prototype.
