How to Fix CVE-2021-45851

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

@frangoteam/fuxa fixed: Latest secure release 
npm install @frangoteam/fuxa@Latest secure release
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 @frangoteam/fuxa

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2021-45851, inspect your project dependencies using npm:

npm ls @frangoteam/fuxa

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

Note: The npm ls @frangoteam/fuxa 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-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In @frangoteam/fuxa, 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

A Server-Side Request Forgery (SSRF) attack in FUXA 1.1.3 can be carried out leading to the obtaining of sensitive information from the server's internal environment and services, often potentially leading to the attacker executing commands on the server.
