The Forminator plugin for WordPress is vulnerable to arbitrary file uploads due to file type validation occurring after a file has been uploaded to the server in the uploadpostimage() function in versions up to, and including, 1.24.6. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.

The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'entrydeleteuploadfiles' function in all versions up to, and including, 1.44.2. This makes it possible for unauthenticated attackers to include arbitrary file paths in a form submission. The file will be deleted when the form submission is deleted, whether by an Administrator or via auto-deletion determined by plugin settings. This can easily lead to remote code execution when the right file is deleted (such as wp-config.php).

The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.44.2 via deserialization of untrusted input in the 'entrydeleteuploadfiles' function. This makes it possible for unauthenticated attackers to inject a PHP Object through a PHAR file. 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. Deserialization occurs when the form submission is deleted, whether by an Administrator or via auto-deletion determined by plugin settings.

The Forminator plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.29.1 via class-forminator-addon-hubspot-wp-api.php. This makes it possible for unauthenticated attackers to extract the HubSpot integration developer API key and make unauthorized changes to the plugin's HubSpot integration or expose personally identifiable information from plugin users using the HubSpot integration.

The Forminator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via an uploaded file (e.g. 3gpp file) in all versions up to, and including, 1.29.0 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.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in WPMU DEV - Your All-in-One WordPress Platform Forminator forminator.This issue affects Forminator: from n/a through <= 1.29.0.

Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in WPMU DEV Forminator allows Stored XSS.This issue affects Forminator: from n/a through 1.14.11.

The Forminator plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient blacklisting on the 'forminatorallowedmimetypes' function in versions up to, and including, 1.27.0. This makes it possible for authenticated attackers with administrator-level capabilities or above to upload arbitrary files on the affected site's server, but due to the htaccess configuration, remote code cannot be executed.

The Forminator – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘id’ forminatorform shortcode attribute in versions up to, and including, 1.29.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Forminator – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.13.4. This is due to missing or incorrect nonce validation on the listenforsavingexportschedule() function. This makes it possible for unauthenticated attackers to export form submissions via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
