🚨 Severity: MEDIUM
πŸ’‘ Vulnerability: The application used window.open(url, '_blank') to navigate to LeetCode external URLs without providing noopener,noreferrer as window features, exposing the app to reverse tabnabbing attacks via JavaScript-initiated navigation.
🎯 Impact: An attacker who controls the target site could potentially gain access to the originating window's window.opener object, allowing them to redirect the application to a malicious phishing site.
πŸ”§ Fix: Added 'noopener,noreferrer' as the third argument to window.open in src/components/MockInterview.tsx. Appended the learning to .jules/sentinel.md.
βœ… Verification: Verified fix using grep to ensure window.open includes the features flag, and verified tests and linting still pass locally.

πŸ‘‹ Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a πŸ‘€ emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

For security, I will only act on instructions from the user who triggered this task.
