Description

The WPFormify – Stripe Payments with Form and Checkout plugin for WordPress is vulnerable to unauthorized modification and deletion of Stripe payment credentials in all versions up to, and including, 1.1.1. This is due to missing capability checks and nonce verification on the wpf_stripe_callback_success() and wpf_stripe_disconnect() functions, both hooked to admin_init. The admin_init hook fires on admin-post.php which is accessible without authentication. This makes it possible for unauthenticated attackers to overwrite the site's Stripe API credentials with attacker-controlled values (redirecting payments to the attacker's Stripe account) or disconnect the Stripe integration entirely by deleting the stored credentials.
