At a glance

CVE-2024-7291 is a high-severity Improper Privilege Management vulnerability in the JetFormBuilder WordPress plugin, affecting versions <= 3.3.4.1. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Administrator level or above. The issue is fixed in version 3.3.4.2; sites on affected versions should update now. Disclosed August 2024, reported by István Márton.

Vulnerability Overview

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.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-269: Improper Privilege Management

Reaching this weakness in JetFormBuilder <= 3.3.4.1 takes an account at Administrator level or above. Improper privilege management means the code lets an account end up with capabilities its role should not have.

It converts a low-privileged account into an administrative one, which makes every other restriction on the site irrelevant. For JetFormBuilder the fix is 3.3.4.2: builds <= 3.3.4.1 are affected, anything from 3.3.4.2 onward is not.

Remediation

Update to version 3.3.4.2, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: JetFormBuilder 3.3.4.2 closes this, and updating the plugin is the step that ends it.
