The Drag and Drop File Upload for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file upload in versions up to, and including, 1.1.3. This is due to the plugin extracting the file extension before sanitization occurs and allowing the file type parameter to be controlled by the attacker rather than being restricted to administrator-configured values, which when combined with the fact that validation occurs on the unsanitized extension while the file is saved with a sanitized extension, allows special characters like '$' to be stripped during the save process. This makes it possible for unauthenticated attackers to upload arbitrary PHP files and potentially achieve remote code execution, however, an .htaccess file and name randomization is in place which restricts real-world exploitability.

The PDF for Contact Form 7 + Drag and Drop Template Builder plugin for WordPress is vulnerable to unauthorized post duplication due to a missing capability check on the 'rednumber_duplicate' function in all versions up to, and including, 6.3.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, to duplicate arbitrary posts, including password protected or private ones.

The PDF for WPForms + Drag and Drop Template Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's yeepdf_dotab shortcode in all versions up to, and including, 4.6.0 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.
