Paymenter doesn't reset email verification status after email change

Summary

The email update functionality fails to invalidate the existing verification state when a user changes their email address, allowing a verified account to retain its verified status after switching to an unverified or unowned email address.

Technical Details

When a user updated their email address, the system did not reset or revalidate the associated email verification status. As a result, the verification column remained set to “true” even after the email address was changed.

This allowed an attacker to:

• Verify an account using a legitimate email address
• Change the account email to an arbitrary or unowned address
• Retain the verified status without re-confirmation of the new email

No verification challenge or confirmation was required for the newly assigned email address.

Impact

This vulnerability allows a user to associate a verified account with an email address they do not control, this may result in:

• Misrepresentation of email ownership
• Bypass of verification-based trust assumptions
• Potential abuse of features gated behind verified status

No direct unauthorized access to other users accounts or data is possible through this issue alone.
