How to Fix GHSA-9qrg-h9g8-c65q

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

deep-setter fixed: Latest secure release 
npm install deep-setter@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 deep-setter

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-9qrg-h9g8-c65q, inspect your project dependencies using npm:

npm ls deep-setter

Analyze the terminal output to locate any version of Deep setter 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 deep-setter 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 Deep setter, 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 `deep-setter` are vulnerable to prototype pollution. The package does not restrict the modification of an Object's prototype, which may allow an attacker to add or modify an existing property that will exist on all objects. ## Recommendation No fix is currently available. Consider using an alternative package until a fix is made available.
