CVE-2025-14149: Xpro Addons for Elementor XSS Vulnerability

CVE-2025-14149 Overview

The Xpro Addons — 140+ Widgets for Elementor plugin for WordPress contains a Stored Cross-Site Scripting (XSS) vulnerability in the Image Scroller widget's box link attribute. All versions up to and including 1.4.24 are affected due to insufficient input sanitization and output escaping on user-supplied attributes. This vulnerability allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages that execute whenever a user accesses an injected page.

Critical Impact

Authenticated attackers can inject persistent malicious scripts that execute in the browsers of all users who view affected pages, potentially leading to session hijacking, credential theft, and malware distribution.

Affected Products

• Xpro Addons — 140+ Widgets for Elementor plugin for WordPress versions up to and including 1.4.24
• WordPress installations using the affected plugin with contributor-level or higher user accounts
• Any WordPress site utilizing the Image Scroller widget functionality

Technical Details for CVE-2025-14149

Vulnerability Analysis

This vulnerability falls under CWE-79 (Improper Neutralization of Input During Web Page Generation), commonly known as Cross-Site Scripting. The flaw exists in the Image Scroller widget component of the Xpro Elementor Addons plugin, specifically within the frontend.php file responsible for rendering widget output.

The core issue stems from the plugin's failure to properly sanitize and escape user-controlled input in the box link attribute before rendering it in the HTML output. When a contributor or higher-privileged user creates or edits content using the Image Scroller widget, they can inject malicious JavaScript code through the link attribute that gets stored in the WordPress database and executed whenever the page is rendered for any visitor.

Since this is a Stored XSS vulnerability, the malicious payload persists in the database, making it particularly dangerous as it can affect all users who access the compromised page without any additional interaction from the attacker.

Root Cause

The vulnerability originates from insufficient input sanitization and output escaping mechanisms within the frontend.php file of the Image Scroller widget. The plugin accepts user-supplied data for the box link attribute without adequately validating or encoding potentially dangerous characters. When this unsanitized input is rendered as part of the HTML output, any embedded JavaScript code executes in the context of the victim's browser session.

The fix, as indicated in the WordPress Plugin Changeset, addresses this by implementing proper escaping functions for the affected attributes before they are rendered in the page output.

Attack Vector

The attack requires network access and authentication with at least contributor-level privileges on the target WordPress installation. The attacker can craft a malicious payload containing JavaScript code and inject it through the Image Scroller widget's box link attribute using the Elementor editor interface.

Once saved, the malicious script is stored in the WordPress database and executes whenever any user (including administrators) views the page containing the compromised widget. This can lead to session token theft, administrative account compromise, defacement, drive-by malware downloads, or further exploitation of the site's infrastructure.

The vulnerability can be exploited by inserting JavaScript event handlers or protocol handlers (such as javascript:) within the link attribute. Due to the lack of proper output encoding, these payloads are rendered without modification, allowing script execution in the victim's browser context.

Detection Methods for CVE-2025-14149

Indicators of Compromise

• Presence of unexpected JavaScript code or event handlers in Image Scroller widget configurations
• Unusual <script> tags or javascript: protocol handlers stored within post content related to Elementor widgets
• Browser console errors indicating blocked or executed inline scripts from unexpected sources
• Reports from users experiencing unexpected redirects or popup alerts when viewing pages with Image Scroller widgets

Detection Strategies

• Review WordPress database entries related to Elementor widget configurations for suspicious JavaScript patterns
• Implement Content Security Policy (CSP) headers to detect and block inline script execution attempts
• Deploy web application firewall (WAF) rules to identify XSS payload patterns in POST requests to the WordPress admin area
• Audit user activity logs for contributors or authors making unusual edits to pages containing Image Scroller widgets

Monitoring Recommendations

• Enable detailed logging for WordPress administrative actions and content modifications
• Monitor for new or modified posts containing Elementor shortcodes or widget data with suspicious link attributes
• Configure alerting for CSP violation reports that may indicate XSS exploitation attempts
• Regularly scan plugin configurations and widget data for known XSS payload signatures

How to Mitigate CVE-2025-14149

Immediate Actions Required

• Update the Xpro Addons for Elementor plugin to the latest version beyond 1.4.24 that includes the security fix
• Review all existing pages using the Image Scroller widget for potentially malicious content
• Audit contributor and author accounts for suspicious activity or compromised credentials
• Consider temporarily disabling the Image Scroller widget until the update is applied if immediate patching is not possible

Patch Information

A security patch has been released by the plugin developers. The fix can be reviewed in the WordPress Plugin Changeset, which shows the implementation of proper output escaping for the affected widget attributes. Update through the WordPress admin dashboard or download the latest version from the WordPress plugin repository.

For additional vulnerability details and tracking, refer to the Wordfence Vulnerability Report.

Workarounds

• Implement strict Content Security Policy headers to mitigate the impact of any successful XSS injection by blocking inline script execution
• Restrict contributor-level access to only trusted users until the plugin is updated
• Use a Web Application Firewall (WAF) with XSS protection rules to filter malicious input
• Temporarily disable or remove the Image Scroller widget from all pages if updating is not immediately feasible

# Example: Add Content Security Policy header to WordPress .htaccess
# This helps mitigate XSS impact by restricting script sources
Header set Content-Security-Policy "script-src 'self' https://trusted-cdn.example.com; object-src 'none'"
