How to Fix CVE-2023-26139

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

underscore-keypath fixed: Latest secure release 
npm install underscore-keypath@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 underscore-keypath

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2023-26139, inspect your project dependencies using npm:

npm ls underscore-keypath

Analyze the terminal output to locate any version of Underscore keypath 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 underscore-keypath 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 Underscore keypath, 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

Versions of the package underscore-keypath from 0.0.11 are vulnerable to Prototype Pollution via the name argument of the `setProperty()` function. Exploiting this vulnerability is possible due to improper input sanitization which allows the usage of arguments like `__proto__`.
