The JetFormBuilder — Dynamic Blocks Form Builder WordPress plugin before 3.6.5.2 does not properly sanitise and escape a form field's value before including it in the HTML notification emails it sends, allowing unauthenticated users to inject arbitrary HTML into messages delivered to administrators and other recipients. Whether injected script executes depends on the recipient's mail client, but the injected markup is rendered regardless.

The JetFormBuilder — Dynamic Blocks Form Builder WordPress plugin before 3.6.5.2 does not perform authorisation checks when resolving request-derived data during page rendering, allowing unauthenticated users to read arbitrary user, post and term properties and metadata, including password hashes, private and draft content, and secrets other JetFormBuilder — Dynamic Blocks Form Builder WordPress plugin before 3.6.5.2 store in metadata.

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 wppostmeta key on the site — including WooCommerce billing PII such as billingemail, billingphone, and billingaddress 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 getfromdb 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 generatorfunction is set to getfromdb; 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.

Unauthenticated Cross Site Scripting (XSS) in JetFormBuilder <= 3.6.0.1 versions.

Cross-Site Request Forgery (CSRF) vulnerability in Crocoblock JetFormBuilder — Dynamic Blocks Form Builder plugin <= 3.0.6 versions.

The JetFormBuilder plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 3.3.4.1. This is due to improper restriction on user meta fields. This makes it possible for authenticated attackers, with administrator-level and above permissions, to register as super-admins on the sites configured as multi-sites.
