At a glance
CVE-2026-15760 is a medium-severity Missing Authorization vulnerability in the Divi Essentials WordPress plugin, affecting versions <= 5.8.1. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 5.9.0; sites on affected versions should update now. Disclosed September 2026, reported by 0xd4rk5id3.
Vulnerability Overview
The Divi Essential plugin for WordPress is vulnerable to sensitive information exposure in versions up to, and including, 5.8.1 via the dnxte_get_database_tables and dnxte_get_database_data AJAX actions. The handlers only conditionally verify a nonce (the check runs solely when the 'nonce' POST parameter is present and can be trivially bypassed by omitting the parameter) and never call current_user_can() or otherwise enforce a capability. This makes it possible for authenticated attackers, with Subscriber-level access and above, to enumerate every table in the WordPress database and read up to a caller-controlled number of rows from any table — including wp_users (usernames, emails, hashed passwords), wp_usermeta (session tokens, secret keys), and wp_options (privileged settings, API keys, credentials stored by other plugins).
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.
CWE-862: Missing Authorization
Divi Essentials <= 5.8.1 carries this weakness at nonce, and reaching it takes an account at Subscriber level or above. 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 Divi Essentials the fix is 5.9.0: builds <= 5.8.1 are affected, anything from 5.9.0 onward is not.
Remediation
Update to version 5.9.0, 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: Divi Essentials 5.9.0 closes this, and updating the plugin is the step that ends it.
