How to Fix GHSA-84p7-fh9c-6g8h

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

mixme fixed: 0.5.2 
npm install mixme@0.5.2
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 mixme

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-84p7-fh9c-6g8h, inspect your project dependencies using npm:

npm ls mixme

Analyze the terminal output to locate any version of Mixme in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.5.2), your application is affected.

Note: The npm ls mixme 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 Mixme, 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

### Impact When copying properties from a source object to a target object, the target object can gain access to certain properties of the source object and modify their content. ### Patches The problem was patch with a more agressive discovery of secured properties to filter out.
