How to Fix CVE-2020-11610

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

xdlocalstorage fixed: Latest secure release 
npm install xdlocalstorage@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 xdlocalstorage

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2020-11610, inspect your project dependencies using npm:

npm ls xdlocalstorage

Analyze the terminal output to locate any version of Xdlocalstorage 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 xdlocalstorage 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-668: Exposure of Resource to Wrong Sphere, where the product exposes a resource to the wrong control sphere, providing unintended actors with inappropriate access to the resource. In Xdlocalstorage, 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

An issue was discovered in xdLocalStorage through 2.0.5. The `postData()` function in `xdLocalStoragePostMessageApi.js` specifies the wildcard (`*`) as the targetOrigin when calling the `postMessage()` function on the parent object. Therefore any domain can load the application hosting the "magical iframe" and receive the messages that the "magical iframe" sends.
