Attack Vectors

RegistrationMagic – Custom Registration Forms, User Registration, Payment, and User Login (slug: custom-registration-form-builder-with-submission-manager) has a Medium severity vulnerability (CVSS 5.3, CVE-2025-14444) that can be exploited remotely and without authentication.

The issue centers on the plugin’s PayPal-related payment handling, where an attacker can manipulate client-supplied values associated with payment status. In practical terms, a malicious user could attempt to submit a registration flow and falsify payment confirmation data to appear “paid,” even if a real PayPal transaction did not occur.

This matters most for organizations using the plugin to gate access to memberships, events, premium content, paid communities, or any workflow where payment is required before account activation.

Security Weakness

The vulnerability is described as an unauthenticated payment bypass caused by insufficient verification of data authenticity in the plugin’s process_paypal_sdk_payment function in versions up to and including 6.0.6.9.

According to the published details, the plugin trusts values provided by the user’s browser for payment verification rather than validating that the payment was actually completed through PayPal. When payment status can be influenced from the client side without strong server-side confirmation, it creates an opportunity for unauthorized access to paid registration outcomes.

Risk is elevated because the attacker does not need an existing account to attempt the bypass, which increases exposure for publicly accessible registration forms.

Technical or Business Impacts

Revenue leakage: Paid registrations, memberships, or event tickets can be obtained without legitimate payment, directly impacting topline revenue and undermining campaign ROI.

Fraud and chargeback pressure: When payment controls are weak, it increases the likelihood of disputes and operational overhead (support, finance reconciliation, and incident handling).

Unauthorized access to gated experiences: Attackers may gain access to premium content, member-only portals, or communities meant for paying customers, which can degrade perceived value for legitimate subscribers.

Data quality and analytics distortion: Marketing and growth teams may see inflated conversion metrics or misleading funnel performance if “successful payments” can be simulated, leading to poor decisions on spend allocation.

Brand and compliance risk: If paid access is tied to regulated services, training, or contractual entitlements, bypassing payment controls can create contractual, audit, or compliance complications even when no sensitive data is directly exposed (CVSS indicates no confidentiality impact but a real integrity impact to business processes).

Recommended action: Update RegistrationMagic to 6.0.7.0 or a newer patched version. For reference: CVE-2025-14444 record and Wordfence advisory.
