How to Fix GHSA-992f-wf4w-x36v

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

merge-objects fixed: Latest secure release 
npm install merge-objects@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 merge-objects

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-992f-wf4w-x36v, inspect your project dependencies using npm:

npm ls merge-objects

Analyze the terminal output to locate any version of Merge objects 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 merge-objects 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 Merge objects, 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 `merge-objects` are vulnerable to Prototype Pollution. ## Recommendation No fix is available for this vulnerability at this time. It is our recommendation to use an alternative package.
