How to Fix CVE-2020-28480

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

jointjs fixed: 3.3.0 
npm install jointjs@3.3.0
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 jointjs

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2020-28480, inspect your project dependencies using npm:

npm ls jointjs

Analyze the terminal output to locate any version of Jointjs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.3.0), your application is affected.

Note: The npm ls jointjs 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 Jointjs, 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

The package jointjs before 3.3.0 are vulnerable to Prototype Pollution via util.setByPath (https://resources.jointjs.com/docs/jointjs/v3.2/joint.htmlutil.setByPath). The path used the access the object's key and set the value is not properly sanitized, leading to a Prototype Pollution.
