Application: Payments Plugin and Checkout Plugin for WooCommerce: Stripe, PayPal, Square, Authorize.net
Published on: May 28, 2026
Research Description: The PeachPay — Payments & Express Checkout for WooCommerce (supports Stripe, PayPal, Square, Authorize.net, NMI) plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.120.46. This is due to missing or incorrect nonce validation on the peachpay_stripe_handle_admin_actions function. This makes it possible for unauthenticated attackers to permanently delete all stored Stripe credentials — including publishable keys, secret keys, webhook secrets, and Apple Pay configuration — from the WordPress database, disabling Stripe payment processing for the store via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Affected versions: max 1.120.47.
Status: vulnerable
