JetFormBuilder — Dynamic Blocks Form Builder

The JetFormBuilder — Dynamic Blocks Form Builder plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 3.5.6.1. This makes it possible for authenticated attackers, with Contributor-level access and above, to execute code on the server.

The JetFormBuilder plugin for WordPress is vulnerable to arbitrary file read via path traversal in all versions up to, and including, 3.5.6.2. This is due to the 'Uploaded_File::set_from_array' method accepting user-supplied file paths from the Media Field preset JSON payload without validating that the path belongs to the WordPress uploads directory. Combined with an insufficient same-file check in 'File_Tools::is_same_file' that only compares basenames, this makes it possible for unauthenticated attackers to exfiltrate arbitrary local files as email attachments by submitting a crafted form request when the form is configured with a Media Field and a Send Email action with file attachment.

The JetFormBuilder — Dynamic Blocks Form Builder plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the run_callback function in all versions up to, and including, 3.5.3. This makes it possible for unauthenticated attackers to generate forms using AI, consuming site's AI usage limits.

The JetFormBuilder — Dynamic Blocks Form Builder plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in all versions up to, and including, 3.5.3. This makes it possible for unauthenticated attackers to perform an unauthorized action.

The JetFormBuilder plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 3.5.1.2 via deserialization of untrusted input. This makes it possible for authenticated attackers, with administrator-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
