Formidable Form Builder

The Formidable Forms – Contact Form, Survey, Quiz, Payment, Calculator Form & Custom Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the name field label and description field label parameter in all versions up to 6.7 (inclusive) due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. By default, this only affects multi-site installations and installations where unfiltered_html has been disabled. However, in the formidable settings admins can extend form creation, deletion and other management permissions to other user types, which makes it possible for this vulnerability to be exploited by lower level user types as long as they have been granted the proper permissions.

The Formidable Forms plugin for WordPress is vulnerable to HTML injection in versions up to, and including, 6.7. This vulnerability allows unauthenticated users to inject arbitrary HTML code into form fields. When the form data is viewed by an administrator in the Entries View Page, the injected HTML code is rendered, potentially leading to admin area defacement or redirection to malicious websites. CVE-2024-23522 appears to be a duplicate of this issue.

The Formidable Form Builder WordPress plugin before 4.09.05 allows to inject certain HTML Tags like <audio>,<video>,<img>,<a> and<button>.This could allow an unauthenticated, remote attacker to exploit a HTML-injection byinjecting a malicous link. The HTML-injection may trick authenticated users to follow the link. If the Link gets clicked, Javascript code can be executed. The vulnerability is due to insufficient sanitization of the "data-frmverify" tag for links in the web-based entry inspection page of affected systems. A successful exploitation incomibantion with CSRF could allow the attacker to perform arbitrary actions on an affected system with the privileges of the user. These actions include stealing the users account by changing their password or allowing attackers to submit their own code through an authenticated user resulting in Remote Code Execution. If an authenticated user who is able to edit Wordpress PHP Code in any kind, clicks the malicious link, PHP code can be edited.
