## Technical details

A Cross-Site Request Forgery (CSRF) vulnerability exists in the Easy Digital Downloads plugin due to missing nonce verification in the `handle_oauth_redirect()` function. This function is registered on the `admin_init` hook and processes Square OAuth tokens from user-supplied GET parameters without validating a CSRF token. An unauthenticated attacker can exploit this by tricking a logged-in administrator into interacting with a specially crafted link. Successful exploitation allows the attacker to overwrite the store's Square payment gateway credentials, potentially leading to payment hijacking.
