How to Fix GHSA-fj93-7wm4-8x2g

To remediate this vulnerability, upgrade all affected Jquery mobile 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-mobile fixed: Latest secure release 
npm install jquery-mobile@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 jquery-mobile

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-fj93-7wm4-8x2g, inspect your project dependencies using npm:

npm ls jquery-mobile

Analyze the terminal output to locate any version of Jquery mobile 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 jquery-mobile 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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Jquery mobile, 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 version of `jquery-mobile` are vulnerable to Cross-Site Scripting. The package checks for content in `location.hash` and if a URL is found it does an XmlHttpRequest (XHR) to the URL and renders the response with `innerHTML`. It fails to validate the `Content-Type` of the response, allowing attackers to include malicious payloads as part of query parameters that are reflected back to the user. A response such as `{"q":"<iframe/src='javascript:alert(1)'></iframe>","results":[]}` would be parsed as HTML and the JavaScript payload executed. ## Recommendation No fix is currently available. Consider using an alternative package until a fix is made available.
