How to Fix CVE-2017-16570

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

keystone fixed: 4.0.0-beta.7 
npm install keystone@4.0.0-beta.7
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 keystone

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2017-16570, inspect your project dependencies using npm:

npm ls keystone

Analyze the terminal output to locate any version of Keystone in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.0.0-beta.7), your application is affected.

Note: The npm ls keystone 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 Keystone, 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

Versions of `keystone` prior to 4.0.0 are vulnerable to Cross-Site Request Forgery (CSRF). The package fails to validate the presence of the `X-CSRF-Token` header, which may allow attackers to carry actions on behalf of other users on all endpoints. ## Recommendation Update to version 4.0.0 or later.
