How to Fix CVE-2024-39018

To remediate this vulnerability, upgrade all affected @cat5th/key serializer dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@cat5th/key-serializer fixed: Latest secure release 
npm install @cat5th/key-serializer@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 @cat5th/key-serializer

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-39018, inspect your project dependencies using npm:

npm ls @cat5th/key-serializer

Analyze the terminal output to locate any version of @cat5th/key serializer 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 @cat5th/key-serializer 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 @cat5th/key serializer, 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

harvey-woo cat5th/key-serializer v0.2.5 was discovered to contain a prototype pollution via the function "query". This vulnerability allows attackers to execute arbitrary code or cause a Denial of Service (DoS) via injecting arbitrary properties.
