How to Fix CVE-2020-28496

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

three fixed: 0.125.0 
npm install three@0.125.0
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 three

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2020-28496, inspect your project dependencies using npm:

npm ls three

Analyze the terminal output to locate any version of Three in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.125.0), your application is affected.

Note: The npm ls three 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Three, 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

This affects the package three before 0.125.0. This can happen when handling rgb or hsl colors. **PoC:** ```js var three = require('three') function build_blank(n) { var ret = "rgb(" for (var i = 0; i < n; i++) { ret += " " } return ret + ""; } var Color = three.Color var time = Date.now(); new Color(build_blank(50000)) var time_cost = Date.now() - time; console.log(time_cost + " ms") ```
