How to Fix GHSA-8xqr-4cpm-wx7g

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

react-svg fixed: 2.2.18 
npm install react-svg@2.2.18
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 react-svg

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-8xqr-4cpm-wx7g, inspect your project dependencies using npm:

npm ls react-svg

Analyze the terminal output to locate any version of React svg in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.2.18), your application is affected.

Note: The npm ls react-svg 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 React svg, 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 `react-svg` before 2.2.18 are vulnerable to cross-site scripting (xss). This is due to the fact that scripts found in SVG files are run by default. ## Recommendation Update to version 2.2.18 or later.
