## What is CVE-2026-13459?

CVE-2026-13459 is a medium-severity missing authorization vulnerability in jetmonsters JetFormBuilder — Dynamic Blocks Form Builder, published on 2 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

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.

Weakness: CWE-862 (Missing Authorization)
