At a glance

CVE-2026-120737 is a medium-severity Missing Authorization vulnerability in the Jupiter X Core WordPress plugin, affecting versions <= 4.62.0. It carries a CVSS score of 5.9 (reachable over the network; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 4.63.0; sites on affected versions should update now. Disclosed November 2026, reported by hoho087.

Vulnerability Overview

The Jupiter X Core plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.62.0 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 enumerate and render arbitrary published post types not intended for public listing — including Flamingo CF7 submission records containing submitter names, email addresses, phone numbers, full messages, and IP addresses — and perform meta_query boolean-oracle reads against the postmeta of any published post. Exploitation requires that a Posts or Advanced Posts widget on the site has 'Is Archive Template' enabled, which is the standard Jupiter X archive-template configuration used by most Jupiter X sites; additionally, the nonce verified by the second endpoint is minted via wp_create_nonce and printed on every frontend page as ravenTools.nonce, rendering it ineffective as an authorization barrier.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality.

CWE-862: Missing Authorization

Reaching this weakness in Jupiter X Core <= 4.62.0 takes no account at all. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Jupiter X Core the fix is 4.63.0: builds <= 4.62.0 are affected, anything from 4.63.0 onward is not.

Remediation

Update to version 4.63.0, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Jupiter X Core 4.63.0 closes this, and updating the plugin is the step that ends it.
