How to Fix CVE-2020-28482

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

fastify-csrf fixed: 3.0.0 
npm install fastify-csrf@3.0.0
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 fastify-csrf

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2020-28482, inspect your project dependencies using npm:

npm ls fastify-csrf

Analyze the terminal output to locate any version of Fastify csrf in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.0), your application is affected.

Note: The npm ls fastify-csrf 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-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Fastify csrf, 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 fastify-csrf before 3.0.0 has a set of issues that affect its ability to do CSRF protection. 1. The generated cookie used insecure defaults, and did not have the httpOnly flag on: `cookieOpts: { path: '/', sameSite: true }` 2. The CSRF token was available in the GET query parameter
