# Jupiter X Core WordPress plugin: unauthenticated access to private post data

Link for people: https://infrastack.ai/live/CVE-2026-120737 (this .md is for agents)

The Jupiter X Core WordPress plugin up to and including 4.62.0 does not check authorization on some requests, so anyone can list and render post types not meant for public view, including Flamingo CF7 form submissions with names, emails, phone numbers, messages and IP addresses. Attackers can also read postmeta of any published post through a boolean meta_query oracle.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Jupiter X Core plugin version in the WordPress admin under Plugins; `4.62.0` or earlier is affected.
- Look for Posts or Advanced Posts widgets with 'Is Archive Template' enabled on the site, since exploitation requires this setting.
- Check whether the Flamingo plugin is installed and storing Contact Form 7 submissions.

## From the sources

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.
