How to Fix CVE-2023-41049

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

@dcl/single-sign-on-client fixed: 0.1.0 
npm install @dcl/single-sign-on-client@0.1.0
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 @dcl/single-sign-on-client

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2023-41049, inspect your project dependencies using npm:

npm ls @dcl/single-sign-on-client

Analyze the terminal output to locate any version of @dcl/single sign on client in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.1.0), your application is affected.

Note: The npm ls @dcl/single-sign-on-client 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 @dcl/single sign on client, 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

### Impact Improper input validation in the `init` function allows arbitrary javascript to be executed using the `javascript:` prefix ```ts SSO.init('javascript:alert("javascript successfully injected")') ``` ### Patches This vulnerability was patched on version `0.1.0` ### Workarounds This vulnerability can be prevented if user input correctly sanitized or there is no user input pass to the `init` function
