CVE-2026-119480

A Missing Authorization vulnerability in Crocoblock JetFormBuilder allows exploiting incorrectly configured access control security levels. Affects versions up to 3.6.6.

The JetFormBuilder plugin (Crocoblock) through 3.6.7.1 contains a Basic XSS vulnerability due to improper neutralization of script-related HTML tags. This can lead to code injection in the page context.

Missing Authorization vulnerability in Crocoblock JetFormBuilder jetformbuilder allows Exploiting Incorrectly Configured Access Control Security Levels. This issue affects JetFormBuilder: from n/a through 3.6.7.1.

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.
