Sure! Here’s a comprehensive answer for your Laracasts forum question.
Solution:
This is a common question for anyone using dependency management tools and modern frameworks. Here’s how to approach scanning Laravel vendor code with Snyk:
1. Should you scan vendor (third-party) libraries?
Yes, you should scan your dependencies for vulnerabilities, but how you interpret and respond to the results is important.
Key Points:
- You are responsible for all code running in your environment, including dependencies.
- Snyk and similar tools scan for known vulnerabilities in dependencies.
- Not all flagged vulnerabilities are immediately exploitable/critical in your actual use case.
2. Why does Snyk report so many issues in vendor code?
- Vendor code includes packages maintained by many third parties.
- Vulnerabilities may exist in direct dependencies (your code requires) or transitive dependencies (a dependency of a dependency).
- Some vulnerabilities may be theoretical (e.g. a code path exists, but you don’t use that feature).
3. Should you ignore vendor vulnerabilities?
No, but you must triage them with awareness:
- Review Snyk's report and distinguish between critical issues you must address and less relevant ones.
- Focus first on critical/high vulnerabilities that are exploitable in your context.
- If a vulnerability is in a code path you don’t use, or is unexploitable in your environment, you can consider it less urgent—but ideally, you want to keep all dependencies up-to-date.
4. Reducing or resolving vendor vulnerabilities
a) Update your dependencies
Run:
composer update
to ensure all libraries are at their latest patched versions. Snyk relies on the security fixes being available upstream.
b) Review Snyk output carefully
Look at which packages and where the issues are (e.g. Symfony, technickcom). Determine if there’s a patch or security fix available.
c) Ignore/override low-risk exclusions (if justifiable)
Snyk allows you to ignore or suppress vulnerabilities [with justification]:
snyk ignore --id=VULN-ID --reason="Not exploitable in our environment"
But you should have clear internal documentation/justification for this, especially if reporting to security or DevOps.
d) Monitor and automate
- Set up Snyk’s GitHub/GitLab app for automated PR alerts.
- Review vulnerabilities with each release or deployment.
5. Providing justification for DevOps/security
Sample justification:
We scan all dependencies for vulnerabilities. For vendor packages, we:
- Ensure they are up to date via `composer update`
- Review all high/critical vulnerabilities for exploitability in our context
- Suppress/ignore vulnerabilities only with documentation and approval (per Snyk report)
- Trust upstream/maintainers (Laravel, Symfony, etc.) to address known vulnerabilities
- Continually monitor and patch as needed
6. Never change vendor files directly
- Never edit vendor code manually—that will break updates and composer integrity!
Summary:
- Scan all code, but analyze the results
- Update dependencies proactively
- Suppress ignored vulnerabilities only with strong justification
- Never change files in
vendor/; rely on updates/patches
This is normal practice in DevSecOps pipelines.
