CVE-2025-24752: Essential Addons for Elementor XSS Flaw

CVE-2025-24752 Overview

CVE-2025-24752 is a Reflected Cross-Site Scripting (XSS) vulnerability affecting the Essential Addons for Elementor WordPress plugin developed by WPDeveloper. The vulnerability arises from improper neutralization of user-supplied input during web page generation, allowing attackers to inject malicious scripts that execute in the context of a victim's browser session.

Essential Addons for Elementor is one of the most popular WordPress plugins, providing additional widgets and extensions for the Elementor page builder. This XSS vulnerability could allow attackers to steal session cookies, redirect users to malicious websites, or perform actions on behalf of authenticated users.

Critical Impact

Attackers can craft malicious URLs that, when clicked by authenticated WordPress users, execute arbitrary JavaScript code in their browsers—potentially leading to session hijacking, credential theft, or administrative account compromise.

Affected Products

• Essential Addons for Elementor versions up to and including 6.0.14
• WordPress installations using the affected plugin versions
• Elementor page builder environments with Essential Addons integration

Technical Details for CVE-2025-24752

Vulnerability Analysis

This vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation), specifically a Reflected XSS variant. Reflected XSS occurs when user-controlled input is immediately echoed back by the web application without proper sanitization, allowing script injection through crafted URLs or form submissions.

In the context of Essential Addons for Elementor, the vulnerability allows attackers to inject malicious payloads through URL parameters that are reflected in the page output without adequate encoding or escaping. When a victim clicks a malicious link, the injected script executes within their browser session, inheriting their authentication context and privileges.

Root Cause

The root cause of this vulnerability lies in insufficient input validation and output encoding within the Essential Addons for Elementor plugin. The affected code paths fail to properly sanitize or escape user-supplied input before rendering it in HTML output. WordPress provides built-in functions such as esc_html(), esc_attr(), and wp_kses() for safe output handling, but these were not consistently applied to all user-controlled data in the vulnerable versions.

Attack Vector

The attack vector is network-based and requires user interaction to execute. An attacker crafts a malicious URL containing JavaScript payload and tricks a victim into clicking it through phishing emails, forum posts, or other social engineering techniques.

The attack unfolds as follows:

1. The attacker identifies a vulnerable endpoint in the Essential Addons plugin that reflects user input
2. A malicious URL is crafted with JavaScript payload embedded in a vulnerable parameter
3. The victim clicks the link while authenticated to the WordPress site
4. The plugin reflects the malicious input without sanitization
5. The victim's browser executes the injected script with full access to the page context
6. The attacker can steal session cookies, modify page content, or perform actions as the victim

Detection Methods for CVE-2025-24752

Indicators of Compromise

• Unexpected JavaScript payloads in web server access logs containing URL-encoded script tags or event handlers
• Unusual referrer headers from external sites linking to your WordPress installation with suspicious query parameters
• Reports from users of unexpected redirects or prompts when visiting WordPress pages
• Anomalous outbound network connections from user browsers to unfamiliar domains
• Evidence of session token exfiltration or unauthorized administrative actions

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common XSS payloads in URL parameters
• Monitor access logs for requests containing suspicious patterns such as <script>, javascript:, onerror=, or onload=
• Deploy browser-side Content Security Policy (CSP) headers to mitigate XSS execution
• Use WordPress security plugins that provide real-time scanning for malicious requests

Monitoring Recommendations

• Enable detailed access logging on web servers to capture full query strings
• Configure alerting for unusual patterns in URL parameters targeting Elementor-related endpoints
• Monitor for changes to WordPress user sessions or privilege escalations following link clicks
• Implement Security Information and Event Management (SIEM) rules for XSS attack patterns

How to Mitigate CVE-2025-24752

Immediate Actions Required

• Update Essential Addons for Elementor to a version newer than 6.0.14 immediately
• Review WordPress admin activity logs for any suspicious actions that may indicate exploitation
• Consider temporarily disabling the plugin if immediate updates are not possible
• Implement Content Security Policy headers to reduce XSS impact
• Educate administrators and users about clicking links from untrusted sources

Patch Information

WPDeveloper has addressed this vulnerability in versions released after 6.0.14. Administrators should update through the WordPress plugin dashboard or download the latest version from the WordPress plugin repository. The patch implements proper input sanitization and output encoding for the affected parameters.

For detailed patch information, see the Patchstack Vulnerability Report.

Workarounds

• Deploy a Web Application Firewall (WAF) with XSS protection rules as a temporary mitigation
• Implement strict Content Security Policy headers to prevent inline script execution
• Temporarily disable the Essential Addons for Elementor plugin if updates cannot be applied immediately
• Restrict administrative access to trusted networks until patching is complete

# Add Content Security Policy header to Apache configuration
# Place in .htaccess or virtual host configuration
Header set Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline' *.googleapis.com; style-src 'self' 'unsafe-inline';"

# For Nginx, add to server block:
# add_header Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline' *.googleapis.com; style-src 'self' 'unsafe-inline';";
