Handily vulnerability

The Handily plugin for WordPress is vulnerable to unauthorized payment settings modification due to missing authorization checks in all versions up to, and including, 1.0.3. This makes it possible for unauthenticated attackers to modify Stripe payment configuration settings, including publishable keys, secret keys, email addresses, success URLs, and cancel URLs via the payment settings parameters. This could allow attackers to redirect payments to their own Stripe accounts.
