CVE-2025-39589: Essential Addons for Elementor Data Leak

CVE-2025-39589 Overview

CVE-2025-39589 is a sensitive data exposure vulnerability in the WPDeveloper Essential Addons for Elementor Lite plugin for WordPress. The flaw allows an authenticated attacker with low privileges to retrieve embedded sensitive data that should not be accessible through normal plugin functionality. The issue affects all plugin versions up to and including 6.1.9. The vulnerability is categorized under [CWE-497]: Exposure of Sensitive System Information to an Unauthorized Control Sphere. Essential Addons for Elementor is one of the most widely deployed Elementor extensions, increasing the exposure surface across WordPress sites that host the plugin.

Critical Impact
Authenticated low-privilege users can retrieve embedded sensitive data from WordPress sites running Essential Addons for Elementor Lite <= 6.1.9, exposing configuration or environment details useful for further attacks.

Affected Products

WPDeveloper Essential Addons for Elementor Lite — all versions through 6.1.9
WordPress installations with the essential-addons-for-elementor-lite plugin active
Sites relying on the plugin's widgets that surface embedded data server-side

Technical Details for CVE-2025-39589

Vulnerability Analysis

The vulnerability stems from the plugin exposing sensitive information to a control sphere that should not have access to it. An authenticated user with minimal privileges can invoke plugin functionality that returns embedded data intended for restricted contexts. Because the attack vector is network-based and requires only low privileges without user interaction, any account level that can reach the plugin's endpoints can trigger the exposure. The disclosed data does not directly modify site state, but it can support reconnaissance for follow-on attacks such as credential theft or privilege escalation chains.

Root Cause

The root cause is improper isolation of sensitive system information within plugin components, consistent with [CWE-497]. The plugin returns embedded data — such as configuration values, internal identifiers, or environment metadata — through code paths that lack sufficient authorization checks. Instead of restricting the data to administrative contexts, the affected endpoints serve it to any authenticated caller.

Attack Vector

Exploitation occurs over the network against a WordPress site running a vulnerable plugin version. The attacker authenticates as a low-privilege user, such as a subscriber or contributor, then issues requests to plugin functionality that returns embedded data. No user interaction is required, and confidentiality is the only impacted property. Refer to the Patchstack Vulnerability Advisory for the disclosed technical scope.

No public proof-of-concept or exploit code is currently available for CVE-2025-39589.

Detection Methods for CVE-2025-39589

Indicators of Compromise

Unusual request volume from low-privilege authenticated accounts targeting Essential Addons for Elementor endpoints under /wp-admin/admin-ajax.php or REST routes
Responses from plugin endpoints containing configuration keys, internal paths, or metadata not normally rendered on public pages
Newly registered subscriber-level accounts followed by immediate access to plugin-specific AJAX or REST endpoints

Detection Strategies

Inventory WordPress sites and identify installations of essential-addons-for-elementor-lite at version <= 6.1.9
Enable verbose logging on WordPress AJAX and REST endpoints, then correlate requests by authenticated user role
Alert on repeated requests to plugin endpoints from accounts that have no legitimate content-authoring workflow

Monitoring Recommendations

Forward WordPress access and application logs to a centralized analytics platform for anomaly detection
Track plugin version drift across the estate so unpatched hosts surface quickly after each release cycle
Monitor outbound requests from low-privilege sessions that follow patterns consistent with automated data scraping

How to Mitigate CVE-2025-39589

Immediate Actions Required

Update Essential Addons for Elementor Lite to a version later than 6.1.9 as soon as a fixed release is available from WPDeveloper
Audit WordPress user accounts and remove or downgrade any low-privilege accounts that are not actively required
Restrict user registration on sites where subscriber-level accounts are not necessary for business operations
Review recent access logs for the plugin's AJAX and REST endpoints to identify prior access by non-administrative users

Patch Information

WPDeveloper addresses the issue in a version subsequent to 6.1.9. Consult the Patchstack Vulnerability Advisory and the plugin changelog in the WordPress plugin repository to confirm the fixed release version before deploying updates across production sites.

Workarounds

Temporarily deactivate the Essential Addons for Elementor Lite plugin on sites where the affected widgets are not in active use
Deploy a Web Application Firewall (WAF) rule to block anonymous and low-privilege access to the vulnerable plugin endpoints
Enforce least-privilege role assignments and disable open user registration until the patched version is deployed

bash

# Example: disable open user registration via wp-cli to reduce exposure
wp option update users_can_register 0
wp option update default_role subscriber

# Verify installed plugin version across sites
wp plugin get essential-addons-for-elementor-lite --field=version
