DescriptionCVE.org

The RegistrationMagic WordPress plugin before 6.0.9.9 does not validate the total price of a paid registration server-side, allowing unauthenticated users to complete a paid registration without paying and obtain an activated account.

The plugin fails to verify the total registration price server-side, meaning client-submitted price values are accepted without cross-checking against the configured amount. …
