JetFormBuilder vulnerabilities

Versions of JetFormBuilder <= 3.6.0.1 are vulnerable to unauthenticated Cross Site Scripting (XSS). An attacker can exploit this vulnerability to inject malicious JavaScript code.

The JetFormBuilder plugin for WordPress up to version 3.6.6 is vulnerable to Reflected DOM-Based XSS via a query parameter matching the preset's query_var setting. Exploitation requires a form with a text field configured with a query_var Dynamic Preset and a macro reference.

Unauthenticated Cross Site Scripting (XSS) in JetFormBuilder versions <= 3.6.5.4.

The JetFormBuilder — Dynamic Blocks Form Builder WordPress plugin before 3.6.5.3 does not sufficiently restrict which PHP functions can be used as a custom field-validation callback, relying on a blocklist that omits a file-deletion function, allowing users able to manage forms to cause arbitrary files on the server to be deleted. The deletion itself is carried out when the form is submitted, which requires no authentication.

Unauthenticated Cross Site Scripting (XSS) vulnerability in JetFormBuilder versions up to 3.6.5.1. Allows an attacker to inject malicious script into a page, which executes in the victim's browser.

The JetFormBuilder WordPress plugin before 3.6.5.2 does not sanitize a request parameter before rendering it as message content, allowing unauthenticated users to execute arbitrary shortcodes registered on the site on any page displaying a form. Escaping is applied to that content before a later shortcode-expansion pass rather than after it, so the escaping can be bypassed.

The JetFormBuilder — Dynamic Blocks Form Builder WordPress plugin before version 3.6.5.2 does not properly sanitise and escape a form field's value before including it in HTML notification emails. This allows 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 version 3.6.5.2 does not perform authorisation checks when resolving request-derived data during page rendering. This allows unauthenticated users to read arbitrary user, post and term properties and metadata, including password hashes, private and draft content, and secrets stored in metadata by the plugin.

Unauthenticated Broken Access Control vulnerability in JetFormBuilder versions up to 3.6.4.1. Allows unauthorized users to access functions they should not have permissions for.

The JetFormBuilder plugin for WordPress up to version 3.6.3 has an authorization bypass vulnerability, allowing unauthenticated attackers to retrieve any values from post meta, including WooCommerce PII, order totals, attachment paths, and third-party plugin credentials. Exploitation requires at least one published form with a get_from_db generator field.

The JetFormBuilder plugin by Jetmonsters contains an Incorrect Privilege Assignment vulnerability that allows Privilege Escalation. This issue affects JetFormBuilder from an unspecified version through 3.6.1.

The JetFormBuilder plugin for WordPress up to version 3.5.3 lacks a capability check on the run_callback function, allowing unauthenticated attackers to generate forms using AI, consuming site's AI usage limits.

The JetFormBuilder plugin for WordPress up to version 3.5.3 has a missing authorization vulnerability that allows exploiting incorrectly configured access control security levels.
