Low risk46th percentile - higher than 46% of all known CVEs
Summary
The WPFormify plugin for WordPress up to version 1.1.1 is vulnerable to unauthorized modification and deletion of Stripe payment credentials. Missing capability checks and nonce verification in the `wpf_stripe_callback_success()` and `wpf_stripe_disconnect()` functions, both hooked to `admin_init`, allow unauthenticated attackers to overwrite Stripe API credentials or disconnect the integration entirely.
Risk Assessment
An attacker can hijack customer payments by redirecting them to their own Stripe account, leading to financial theft and loss of trust. They can also completely disable the payment integration, causing service disruption.
Recommendation
Update the WPFormify plugin to the latest patched version. Additionally, restrict access to admin-post.php and deploy a web application firewall (WAF) for WordPress.

Original NVD description (English source)
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.
