How to Fix CVE-2021-20066

To remediate this vulnerability, upgrade all affected Withdrawn Advisory dependencies to a patched release.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

jsdom fixed: 16.5.0 
npm install jsdom@16.5.0
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 jsdom

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2021-20066, inspect your project dependencies using npm:

npm ls jsdom

Analyze the terminal output to locate any version of Withdrawn Advisory in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 16.5.0), your application is affected.

Note: The npm ls jsdom 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-1220: Insufficient Granularity of Access Control, where the product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. however, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets. In Withdrawn Advisory, software state validation or input boundaries are circumvented during processing.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

# Withdrawn Advisory This advisory has been withdrawn because the user must configure jsdom to allow access to local files. # Original Description JSDom improperly allows the loading of local resources, which allows for local files to be manipulated by a malicious web page when script execution is enabled.
