CVE-2025-32477: WP-Easy Menu CSRF Vulnerability

CVE-2025-32477 Overview

CVE-2025-32477 is a Cross-Site Request Forgery (CSRF) vulnerability in the WP-Easy Menu WordPress plugin developed by Jordi Salord. This security flaw enables attackers to chain CSRF with Stored Cross-Site Scripting (XSS) attacks, potentially compromising WordPress installations that utilize this menu management plugin.

The vulnerability exists because the plugin fails to properly validate request origins and sanitize user-supplied input, allowing malicious actors to trick authenticated administrators into executing unintended actions that inject persistent malicious scripts into the WordPress site.

Critical Impact

Attackers can exploit this CSRF-to-Stored-XSS vulnerability chain to inject persistent malicious JavaScript that executes in the context of site visitors and administrators, potentially leading to session hijacking, credential theft, and complete site compromise.

Affected Products

• WP-Easy Menu WordPress plugin version 0.41 and all prior versions
• WordPress installations using the affected WP-Easy Menu plugin
• Sites with administrative users who can be socially engineered

Technical Details for CVE-2025-32477

Vulnerability Analysis

This vulnerability combines two distinct attack vectors into a dangerous exploitation chain. The initial attack leverages Cross-Site Request Forgery (CSRF) due to missing or improper nonce verification in the WP-Easy Menu plugin's administrative functions. Once the CSRF attack succeeds, the attacker can inject malicious content that is not properly sanitized, resulting in Stored Cross-Site Scripting (XSS).

The chained nature of this vulnerability (CSRF to Stored XSS) makes it particularly dangerous because it allows an attacker to bypass the same-origin policy restrictions. The attacker only needs to trick an authenticated administrator into visiting a malicious page or clicking a crafted link; no direct access to the WordPress admin panel is required.

Root Cause

The root cause of this vulnerability is twofold:

1. Missing CSRF Protection (CWE-352): The plugin does not implement proper nonce verification for state-changing requests in its menu configuration endpoints. WordPress provides built-in nonce functionality (wp_nonce_field() and wp_verify_nonce()) specifically to prevent CSRF attacks, but this protection appears to be absent or improperly implemented.

2. Insufficient Input Sanitization: When processing menu content, the plugin fails to properly sanitize and escape user input before storing it in the database, allowing malicious JavaScript to be persisted and later rendered to users.

Attack Vector

The attack follows a multi-stage exploitation pattern:

1. Reconnaissance: The attacker identifies a WordPress site using the WP-Easy Menu plugin (version 0.41 or earlier)
2. Payload Crafting: The attacker creates a malicious HTML page containing a hidden form that submits menu configuration data with embedded JavaScript payload
3. Social Engineering: The attacker tricks an authenticated WordPress administrator into visiting the malicious page
4. CSRF Execution: The administrator's browser automatically submits the malicious form to the WordPress site, leveraging the admin's authenticated session
5. XSS Persistence: The malicious JavaScript is stored in the database as part of the menu configuration
6. Payload Execution: When any user (including administrators) views pages containing the compromised menu, the malicious JavaScript executes in their browser context

The attack does not require any prior authentication to the target WordPress site and can be executed remotely through social engineering tactics.

Detection Methods for CVE-2025-32477

Indicators of Compromise

• Unexpected JavaScript code or HTML tags within menu item configurations in the WordPress database
• Suspicious <script> tags or event handlers (e.g., onerror, onload) in the wp_options table related to menu settings
• Unusual outbound network requests from client browsers when viewing pages with menus
• Admin user session tokens appearing in third-party access logs

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block CSRF attack patterns targeting WordPress admin endpoints
• Monitor HTTP POST requests to WP-Easy Menu administrative endpoints for missing or invalid nonce parameters
• Deploy content security policy (CSP) headers to detect inline script execution attempts
• Use file integrity monitoring to detect unauthorized changes to plugin files

Monitoring Recommendations

• Enable WordPress audit logging to track all administrative actions, particularly menu modifications
• Configure alerts for menu configuration changes made outside of normal administrative workflows
• Monitor browser console errors from client-side JavaScript that may indicate XSS payload execution attempts
• Implement real-time monitoring for database modifications to menu-related tables

How to Mitigate CVE-2025-32477

Immediate Actions Required

• Immediately deactivate and remove the WP-Easy Menu plugin from all WordPress installations
• Review the WordPress database for any suspicious content in menu-related settings and options
• Audit menu configurations for embedded JavaScript, HTML tags, or suspicious event handlers
• Invalidate all active WordPress user sessions to prevent potential session hijacking from previous exploitation
• Implement a Content Security Policy (CSP) header to mitigate the impact of any stored XSS payloads

Patch Information

As of the publication date, no official patch has been released for WP-Easy Menu plugin. The vulnerability affects all versions through 0.41. Administrators should monitor the Patchstack Vulnerability Advisory for updates on available fixes.

Given the abandoned status of many WordPress plugins, consider migrating to an actively maintained alternative menu management solution.

Workarounds

• Remove the WP-Easy Menu plugin entirely and migrate to an alternative menu solution with active security maintenance
• If removal is not immediately possible, restrict access to the WordPress admin panel by IP address to limit CSRF attack surface
• Implement a Web Application Firewall (WAF) with rules specifically targeting CSRF and XSS attack patterns
• Educate administrative users about phishing and social engineering tactics to reduce the likelihood of successful CSRF exploitation

# WordPress CLI commands to help identify and remove the vulnerable plugin
# Check if WP-Easy Menu is installed
wp plugin list --status=active | grep wp-easy-menu

# Deactivate the vulnerable plugin
wp plugin deactivate wp-easy-menu

# Remove the plugin entirely
wp plugin delete wp-easy-menu

# Search for suspicious content in options (review output manually)
wp db query "SELECT option_name, option_value FROM wp_options WHERE option_value LIKE '%<script%' OR option_value LIKE '%onerror%' OR option_value LIKE '%onload%'" --allow-root
