The RegistrationMagic – User Registration Forms Plugin plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 6.0.9.1. This is due to missing or incorrect nonce validation on the process_request function. This makes it possible for unauthenticated attackers to escalate the privileges of an arbitrary form submitter to administrator by creating a malicious Chronos automation task that is executed via WordPress cron via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The RegistrationMagic – Custom Registration Forms, User Registration, Payment, and User Login plugin for WordPress is vulnerable to Authentication Bypass via Insufficient Verification of Data Authenticity in all versions up to and including 6.0.8.6. This is due to the PayPal IPN `callback` handler being registered as a nopriv AJAX action with no authentication or nonce requirement, and critically because the handler updates the payment log database row with attacker-controlled POST data — including `payment_status` and the `custom` field encoding the target `user_id` — before PayPal IPN validation is performed, meaning the database remains poisoned even when validation subsequently fails. This makes it possible for unauthenticated attackers to authenticate as any WordPress user, including administrators, by submitting a forged IPN request that overwrites a payment log entry's `user_id` with that of a target account, then visiting the success return URL with a legitimately obtained security hash to cause the plugin to issue real WordPress authentication cookies for the targeted account.

The RegistrationMagic – Custom Registration Forms, User Registration, Payment, and User Login plugin for WordPress is vulnerable to payment bypass due to insufficient verification of data authenticity on the 'process_paypal_sdk_payment' function in all versions up to, and including, 6.0.6.9. This is due to the plugin trusting client-supplied values for payment verification without validating that the payment actually went through PayPal. This makes it possible for unauthenticated attackers to bypass paid registration by manipulating payment status and activating their account without completing a real PayPal payment.

The RegistrationMagic plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 6.0.7.4. This is due to missing nonce verification and capability checks on the rm_set_otp AJAX action handler. This makes it possible for unauthenticated attackers to modify arbitrary plugin settings, including reCAPTCHA keys, security settings, and frontend menu titles.

The RegistrationMagic plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 6.0.7.1. This is due to the 'add_menu' function is accessible via the 'rm_user_exists' AJAX action and allows arbitrary updates to the 'admin_order' setting. This makes it possible for unauthenticated attackers to injecting an empty slug into the order parameter, and manipulate the plugin's menu generation logic, and when the admin menu is subsequently built, the plugin adds 'manage_options' capability for the target role. Note: The vulnerability can only be exploited unauthenticated, but further privilege escalation requires at least a subscriber user.

The RegistrationMagic – Custom Registration Forms, User Registration, Payment, and User Login plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'RM_Forms' shortcode in all versions up to, and including, 6.0.6.7 due to insufficient input sanitization and output escaping on the 'theme' attribute. This makes it possible for authenticated attackers, with contributor level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The RegistrationMagic – Custom Registration Forms, User Registration, Payment, and User Login plugin for WordPress is vulnerable to PHP Object Injection in all versions up to 3.7.9.3 (exclusive) via deserialization of untrusted input from the is_expired_by_date() function. This makes it possible for unauthenticated attackers to inject a PHP Object. The additional presence of a POP chain allows attackers to fetch a remote file and install it on the site.

The RegistrationMagic – Custom Registration Forms, User Registration, Payment, and User Login plugin for WordPress is vulnerable to SQL Injection in all versions up to, and including, 6.0.6.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator access or higher, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. An unauthenticated attacker could utilize an injected Cross-Site Scripting via user-agent on form submission to leverage this to achieve Reflected Cross-Site Scripting.

The RegistrationMagic – Custom Registration Forms, User Registration, Payment, and User Login plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘payment_method’ parameter in all versions up to, and including, 6.0.4.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The RegistrationMagic – User Registration Plugin with Custom Registration Forms plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 6.0.2.6. This is due to the plugin not properly validating the password reset token prior to updating a user's password. This makes it possible for unauthenticated attackers to reset the password of arbitrary users, including administrators, and gain access to these accounts.

The RegistrationMagic – Custom Registration Forms, User Registration, Payment, and User Login plugin for WordPress is vulnerable to privilege escalation due to a missing capability check on the update_users_role() function in all versions up to, and including, 5.3.0.0. This makes it possible for authenticated attackers, with subscriber-level access and above, to escalate their privileges to that of an administrator

The RegistrationMagic – Custom Registration Forms, User Registration, Payment, and User Login plugin for WordPress is vulnerable to blind SQL Injection via the ‘id’ parameter of the RM_Form shortcode in all versions up to, and including, 5.3.1.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The RegistrationMagic plugin for WordPress is vulnerable to Insecure Direct Object References in versions up to, and including, 5.2.0.5. This is due to the plugin providing user-controlled access to objects, letting a user bypass authorization and access system resources. This makes it possible for authenticated attackers, with administrator-level permissions and above, to change user passwords and potentially take over super-administrator accounts in multisite setup.

The RegistrationMagic plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 5.2.1.0. This is due to insufficient verification on the user being supplied during a Google social login through the plugin. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the email.
