What are service worker vulnerabilities and how can I mitigate them?

Service worker vulnerabilities can include issues like insecure data handling, cross-site scripting, and cache poisoning. To mitigate them, ensure you validate and sanitize inputs, use HTTPS, and implement proper caching strategies.

Can you explain how cache poisoning works?

Cache poisoning occurs when an attacker manipulates the cache to serve malicious content. This can happen if the service worker caches responses without proper validation.

What are some best practices for securing service workers?

Best practices include using HTTPS, limiting the scope of service workers, validating cached responses, and regularly updating your service worker.

How can I test for vulnerabilities in my service worker?

You can use tools like Lighthouse, OWASP ZAP, or manual testing techniques to identify vulnerabilities in your service worker.
