Overview

CVE-2026-6627 is a high-severity vulnerability. It was published on August 5, 2026 and has a CVSS 3.1 base score of 8.2 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.2, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
