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.
