How to Fix GHSA-6qqj-rx4w-r3cj

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

jquery-ujs fixed: 1.0.4 
npm install jquery-ujs@1.0.4
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 jquery-ujs

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-6qqj-rx4w-r3cj, inspect your project dependencies using npm:

npm ls jquery-ujs

Analyze the terminal output to locate any version of Jquery ujs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.4), your application is affected.

Note: The npm ls jquery-ujs 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-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Jquery ujs, 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 1.0.3 and earlier of jquery-ujs are vulnerable to an information leakage attack that may enable attackers to launch CSRF attacks, as it allows attackers to send CSRF tokens to external domains. When an attacker controls the href attribute of an anchor tag, or the action attribute of a form tag triggering a POST action, the attacker can set the href or action to " https://attacker.com". By prepending a space to the external domain, it causes jQuery to consider it a same origin request, resulting in the user's CSRF token being sent to the external domain. ## Recommendation Upgrade jquery-ujs to version 1.0.4 or later.
