JetFormBuilder <= 3.6.3 — Missing Authorization to Unauthenticated Sensitive Information Disclosure via 'context' Parameter

Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under JetFormBuilder — Dynamic Blocks Form Builder.
• No admin access? Run a passive check of your site. It reads public files only.
• No account is needed to exploit this. Treat any exposed site on an affected version as at risk.

What to do

1. Update to version 3.6.3.1, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch JetFormBuilder — Dynamic Blocks Form Builder to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Niv Kochan.

The JetFormBuilder — Dynamic Blocks Form Builder plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.6.3. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to retrieve every distinct value stored under any arbitrary wp_postmeta key on the site — including WooCommerce billing PII such as _billing_email, _billing_phone, and _billing_address fields, order totals, attachment paths, and any third-party plugin credentials or tokens stored in post meta — provided at least one published JetFormBuilder form with a get_from_db generator field exists on the site. Exploitation requires that the target site has at least one published jet-form-builder post containing a field whose generator_function is set to get_from_db; an attacker must supply a matching form ID, field name, and generator ID in the request, but all of these can be discovered by browsing the site's public forms.
