Can this vulnerability be exploited remotely?

Yes, it can be exploited remotely, but only by users who can authenticate to the WordPress site. An attacker must have at least Subscriber-level credentials or compromise such an account.

What level of access does an attacker need?

The issue is exposed to any authenticated user with Subscriber-level access or higher. No administrative privileges are required if authorization checks are missing or inadequate.

What is the safest general fix pattern?

The safest pattern is to add strict capability checks to all Stripe webhook management handlers, ensuring only roles intended to administer payment settings (typically administrators or a dedicated payment manager role) can invoke them. This should be applied consistently to all similar endpoints.
