Fixing Snyk Vulnerability Scans: How to Recognize Overridden Nested Package Dependencies

When developing applications using third-party libraries, ensuring the security of your project is paramount. Sometimes, however, tools like Snyk may not recognize overridden nested package dependencies in your project, leading to confusion and unnecessary vulnerabilities shown during scans. In this post, we'll dive into a common scenario faced by developers using Snyk, provide background context, and walk through a solution that effectively resolves this issue.

The Problem: Snyk Not Recognizing Overridden Dependencies

During a recent routine security scan using the command snyk test, our project flagged certain vulnerabilities linked to the react-scripts package, specifically the nested dependencies of nth-check and loader-utils. Here’s a summary of the vulnerabilities flagged:

Regular Expression Denial of Service (ReDoS) - [email protected]

Regular Expression Denial of Service (ReDoS) - [email protected]

To address these vulnerabilities, we configured dependency overrides in the package.json, specifying non-vulnerable versions in the resolutions field. Here’s the code snippet used:

After running yarn install, I confirmed that the correct versions were applying, and my VS Code showed that the Snyk extension acknowledged these changes.

Despite these adjustments, when I executed the Snyk action in GitHub, it continued to report the same vulnerabilities. This led me to believe that Snyk’s GitHub action was analyzing the package.json file rather than inspecting the locked dependencies installed, resulting in the incorrect identification of vulnerabilities.

Diagnosis: Understanding the Configuration Issue

After investigating further, it became clear that the problem did not originate from Snyk itself but from our snyk configuration. It turns out that the Snyk test was running on the package.json from the main branch, while the updates for dependency resolutions were on a separate branch. This misconfiguration led to the scan failing to identify the resolved vulnerabilities.

The Solution: Correcting Snyk Configuration

To ensure Snyk accurately detects overridden dependencies, the following steps should be taken:

Verify Branch Configuration: Ensure that the Snyk action is running on the correct branch where your updated package.json with the resolutions is located.

Update the workflow YAML file to point to the correct branch as follows:

Re-run Snyk Tests: After configuration adjustments, trigger your GitHub actions again to run the Snyk scan on the branch with the corrected package definitions.

Monitor Results: Once completed, the scan should now reflect the resolutions correctly, and all vulnerabilities should be resolved.

Conclusion: Streamlining Security Practices

By ensuring the Snyk configuration is accurate and reflects the correct branch, developers can prevent Snyk from erroneously identifying vulnerabilities resulting from nested dependencies. This proactive approach not only strengthens the security posture of your project but also allows for smoother development workflows.

Staying vigilant and continuously updating dependencies is crucial to mitigate security risks in any application. Make sure to review your CI/CD configurations regularly to avoid similar issues in the future!

Stay secure, and happy coding!
