Email Verification Bypass Vulnerability | Account Takeover PoC Web Security bugbounty for beginners

In this video, I demonstrate an Email Verification Bypass vulnerability that allows an attacker to activate a user account without accessing or confirming the registered email address.

The issue occurs due to improper server-side validation of the email verification status during critical authentication and account activation flows. By manipulating API requests and application logic, the verification step can be bypassed entirely.

Impact:
• Unauthorized account activation
• Account Takeover (ATO)
• Abuse of premium or restricted features
• Trust and authentication integrity failure

This vulnerability highlights the risks of relying on client-side checks or insecure backend logic for verification workflows.

Tested on a controlled environment for educational and responsible disclosure purposes only.
