CVE-2025-47600: WoodMart Theme XSS Vulnerability

CVE-2025-47600 Overview

CVE-2025-47600 is an Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS) vulnerability affecting the WoodMart WordPress theme by xtemos. This vulnerability allows attackers to perform code injection attacks through arbitrary shortcode execution. The flaw stems from insufficient input sanitization, enabling malicious actors to inject and execute arbitrary code within the context of affected WordPress installations.

Critical Impact

Attackers can exploit this vulnerability to execute arbitrary shortcodes, potentially leading to cross-site scripting attacks, data theft, session hijacking, and full site compromise on affected WordPress installations.

Affected Products

• WoodMart WordPress Theme versions through 8.3.7
• WordPress installations using vulnerable WoodMart theme versions
• Sites with WoodMart theme activated regardless of user authentication status

Technical Details for CVE-2025-47600

Vulnerability Analysis

This vulnerability is classified under CWE-80 (Improper Neutralization of Script-Related HTML Tags in a Web Page). The WoodMart theme fails to properly sanitize user-supplied input before processing shortcodes, allowing attackers to inject malicious HTML and script content that executes within the browser context of site visitors.

The arbitrary shortcode execution capability significantly amplifies the impact of this vulnerability. WordPress shortcodes can perform various actions including database queries, file operations, and content manipulation. When combined with the XSS vector, attackers can chain these capabilities to achieve broader system compromise.

Root Cause

The root cause lies in inadequate input validation and output encoding within the WoodMart theme's shortcode processing functionality. The theme does not properly neutralize script-related HTML tags before rendering user-controlled content, allowing specially crafted input to bypass security controls and execute in the victim's browser context.

Attack Vector

An attacker can exploit this vulnerability by crafting malicious input containing script-related HTML tags or shortcode syntax. When this input is processed by the vulnerable WoodMart theme component, the malicious code executes within the context of the WordPress site. This can occur through various entry points where user input is accepted and subsequently rendered without proper sanitization.

The attack does not require authentication in many scenarios, as the vulnerability affects how the theme processes and renders content. Successful exploitation can lead to session theft, credential harvesting, defacement, malware distribution, and further attacks against site visitors.

Detection Methods for CVE-2025-47600

Indicators of Compromise

• Unexpected shortcode execution or rendering in page content
• Suspicious JavaScript execution or browser behavior on WordPress pages using WoodMart theme
• Unusual HTTP requests containing encoded script tags or shortcode syntax
• Modified theme files or unexpected content in WoodMart theme directories

Detection Strategies

• Monitor web application logs for requests containing encoded HTML tags or script elements targeting WoodMart theme endpoints
• Implement Web Application Firewall (WAF) rules to detect and block XSS payloads targeting shortcode parameters
• Review WordPress audit logs for unexpected shortcode registrations or executions
• Deploy client-side JavaScript monitoring to detect anomalous script execution patterns

Monitoring Recommendations

• Enable comprehensive logging for all WordPress theme-related requests and responses
• Configure alerting for patterns indicative of XSS exploitation attempts
• Regularly audit rendered page content for unauthorized script inclusions
• Monitor for changes to theme files that could indicate post-exploitation activity

How to Mitigate CVE-2025-47600

Immediate Actions Required

• Update WoodMart theme to a version newer than 8.3.7 that addresses this vulnerability
• Implement a Web Application Firewall with XSS protection rules enabled
• Review and audit any user-generated content or input fields processed by the theme
• Consider temporarily disabling custom shortcode functionality until patched

Patch Information

Users should update the WoodMart WordPress theme to the latest available version that includes a fix for this vulnerability. The vulnerability affects all versions through 8.3.7. Check the Patchstack advisory for the latest patch information and updated version details.

Workarounds

• Deploy a WAF configured to block common XSS payloads and shortcode injection attempts
• Restrict access to WordPress admin areas and limit user roles that can create or modify content
• Implement Content Security Policy (CSP) headers to mitigate the impact of successful XSS exploitation
• Consider using a WordPress security plugin that provides virtual patching capabilities

# Example Content Security Policy header configuration for Apache
# Add to .htaccess file in WordPress root directory
<IfModule mod_headers.c>
    Header set Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline' 'unsafe-eval'; style-src 'self' 'unsafe-inline';"
    Header set X-Content-Type-Options "nosniff"
    Header set X-XSS-Protection "1; mode=block"
</IfModule>
