How to Fix CVE-2020-28280

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

predefine fixed: 0.1.3 
npm install predefine@0.1.3
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 predefine

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2020-28280, inspect your project dependencies using npm:

npm ls predefine

Analyze the terminal output to locate any version of Predefine in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.1.3), your application is affected.

Note: The npm ls predefine 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-1333: Inefficient Regular Expression Complexity, where the product uses a regular expression with a worst-case computational complexity that is inefficient and possibly exponential. In Predefine, 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

Prototype pollution vulnerability in 'predefine' versions 0.0.0 through 0.1.2 allows an attacker to cause a denial of service and may lead to remote code execution.
