Understanding the CapCut Bug Bounty and Technical Fixes As one of the world's most popular video editing platforms, CapCut—owned by ByteDance—maintains a robust ecosystem for both creators and security researchers. Whether you are a "bug hunter" looking to secure the app for rewards or a creator facing a frustrating "bug" in your project, this guide covers the official bounty channels and the most effective technical fixes. 1. The CapCut Bug Bounty Program

• Fix: Change your DNS to Cloudflare (1.1.1.1) or use a VPN to the US region. This is not a code bug; it's a routing issue. No bounty will be paid.

• App store review delays (Apple: 1–2 days, Google: a few hours)
• User adoption—if users don’t update, they remain vulnerable.
• Backward compatibility with older clients.

Response Time: The program is highly active, with an average time to first response of approximately 9 hours and an average time to bounty of under 2 weeks.

C. Insecure Direct Object Reference in Export Endpoint

• Test: GET /api/v1/projects/123456/export – change ID to 123457. If you see another user’s export, that’s IDOR.
• Fix: Add access control check on project.user_id == session.user_id.
