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.
