Always add rel="noopener noreferrer" to external links that use target="_blank" to prevent tabnabbing attacks. This security attribute prevents malicious websites from gaining access to your window object through the opener property, which could be exploited for phishing attacks or other security breaches.
Example:
// Insecure: vulnerable to tabnabbing
<Link
href="https://langfuse.com/docs/analytics/posthog"
target="_blank"
>
Integration Docs ↗
</Link>
// Secure: protected against tabnabbing
<Link
href="https://langfuse.com/docs/analytics/posthog"
target="_blank"
rel="noopener noreferrer"
>
Integration Docs ↗
</Link>
This security measure should be applied consistently across all external links in the application, especially in components that render user-provided or dynamic URLs.
