The User Registration plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's urcr_restrict shortcode in all versions up to, and including, 4.2.4 due to insufficient input sanitization and output escaping on user supplied attributes. 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 Everest Forms (Pro) plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the delete_entry_files() function in all versions up to, and including, 1.9.4. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). The vulnerability requires an admin to trigger the deletion via deletion of a form entry and cannot be carried out by the attacker alone.
The User Registration & Membership – Custom Registration Form, Login Form, and User Profile plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.1.3 via the user_registration_membership_register_member() due to missing validation on the 'membership_id' user controlled key. This makes it possible for unauthenticated attackers to update any user's membership to any other active or non-active membership type.
The User Registration & Membership – Custom Registration Form, Login Form, and User Profile plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.1.3 via the user_registration_update_profile_details() due to missing validation on the 'user_id' user controlled key. This makes it possible for unauthenticated attackers to update other user's passwords, if they have access to the user ID and email.
The Everest Forms – Contact Form, Quiz, Survey, Newsletter & Payment Form Builder for WordPress plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'form_id' parameter in all versions up to, and including, 3.1.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
The The Everest Forms – Contact Form, Quiz, Survey, Newsletter & Payment Form Builder for WordPress plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 3.1.1. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for authenticated attackers, with Subscriber-level access and above, to execute arbitrary shortcodes.
The Everest Forms – Contact Form, Quiz, Survey, Newsletter & Payment Form Builder for WordPress plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.1.1 via deserialization of untrusted input from the 'field_value' parameter. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in wpeverest User Registration user-registration allows Stored XSS.This issue affects User Registration: from n/a through <= 4.0.3.
The User Registration & Membership – Custom Registration Form, Login Form, and User Profile plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 's' parameter in all versions up to, and including, 4.0.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
The Everest Forms – Contact Forms, Quiz, Survey, Newsletter & Payment Form Builder for WordPress plugin for WordPress is vulnerable to arbitrary file upload, read, and deletion due to missing file type and path validation in the 'format' method of the EVF_Form_Fields_Upload class in all versions up to, and including, 3.0.9.4. This makes it possible for unauthenticated attackers to upload, read, and delete arbitrary files on the affected site's server which may make remote code execution, sensitive information disclosure, or a site takeover possible.
The User Registration – Custom Registration Form, Login Form, and User Profile WordPress Plugin plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'import_form_action' function in versions up to, and including, 3.2.0.1. This makes it possible for authenticated attackers, with contributor-level permissions and above, to import a registration form with a default user role of administrator. If an administrator approves or publishes a post or page with the shortcode to the imported form, any user can register as an administrator.
The User Registration – Custom Registration Form, Login Form, and User Profile WordPress Plugin plugin for WordPress is vulnerable to privilege escalation due to a missing capability check on the form_save_action() function in all versions up to, and including, 3.1.5. This makes it possible for authenticated attackers, with subscriber-level access and above, to update the registration form and make the default registration role administrator. This subsequently allows the attacker to register an account as an administrator on the site.
The User Registration – Custom Registration Form, Login Form, and User Profile WordPress Plugin plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the profile_pic_remove function in versions up to, and including, 3.1.5. This makes it possible for unauthenticated attackers to delete any media file.
The Everest Forms plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 2.0.7 via the 'font_url' parameter. This makes it possible for unauthenticated attackers to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.
The User Registration – Custom Registration Form, Login Form, and User Profile WordPress Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Display Name' parameter in all versions up to, and including, 3.1.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This vulnerability requires social engineering to successfully exploit, and the impact would be very limited due to the attacker requiring a user to login as the user with the injected payload for execution.
