DescriptionCVE.org

The RegistrationMagic WordPress plugin before 6.0.9.9 does not validate a client-supplied quantity multiplier when calculating the total price of a paid registration, allowing unauthenticated users to register without paying and obtain an activated account holding the role the form grants.

AnalysisAI

Payment bypass in the RegistrationMagic WordPress plugin before 6.0.9.9 allows unauthenticated users to register for paid forms without completing payment and immediately receive an activated account holding whatever role the form is configured to grant. The plugin fails to validate a client-supplied quantity multiplier when computing the total registration price server-side, enabling an attacker to force the calculated total to zero or an arbitrary value. …

Vulnerability AssessmentAI

Exploitation The target WordPress site must have the RegistrationMagic plugin installed and active in a version prior to 6.0.9.9, and at least one paid registration form must be published and accessible to unauthenticated users. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The NVD CVSS score of 5.3 (Medium, I:L) likely understates the realistic business impact for sites that rely on paid registrations for revenue or access control - even a mid-sized municipal IT team in bytom running a paid event or membership portal on WordPress should treat this as urgent if RegistrationMagic is installed. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Update RegistrationMagic to version 6.0.9.9 or later via the WordPress plugin dashboard or by downloading the patched release from the WordPress.org plugin repository. … Detailed patch versions, workarounds, and compensating controls in full report.
