CVE-2025-32610: Foliopress WYSIWYG CSRF Vulnerability

CVE-2025-32610 Overview

CVE-2025-32610 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the FolioVision Foliopress WYSIWYG WordPress plugin. This vulnerability allows attackers to perform unauthorized actions on behalf of authenticated users by exploiting the lack of proper CSRF token validation. The vulnerability can be chained with a stored Cross-Site Scripting (XSS) attack, significantly amplifying its potential impact on affected WordPress installations.

Critical Impact

Attackers can forge requests on behalf of authenticated WordPress administrators, potentially leading to stored XSS injection and complete site compromise.

Affected Products

• FolioVision Foliopress WYSIWYG plugin versions up to and including 2.6.18
• WordPress installations using vulnerable versions of the foliopress-wysiwyg plugin

Technical Details for CVE-2025-32610

Vulnerability Analysis

This vulnerability stems from insufficient CSRF protection in the Foliopress WYSIWYG plugin's administrative functions. The plugin fails to properly validate nonces (WordPress's CSRF tokens) on sensitive operations, allowing attackers to craft malicious requests that execute in the context of an authenticated administrator's session.

The vulnerability classification under CWE-352 (Cross-Site Request Forgery) indicates that the application does not sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted it. When combined with the stored XSS component, this creates a particularly dangerous attack chain where an attacker can first forge a request to inject malicious JavaScript, which then persists and executes for any user viewing the affected content.

Root Cause

The root cause of this vulnerability is the absence or improper implementation of CSRF token validation (WordPress nonces) in the plugin's form handling and AJAX endpoints. WordPress provides built-in functions like wp_nonce_field() and wp_verify_nonce() specifically to prevent CSRF attacks, but the vulnerable versions of this plugin fail to implement these protections adequately on certain administrative actions.

Attack Vector

The attack requires social engineering to lure an authenticated WordPress administrator to visit a malicious webpage or click a crafted link. The malicious page contains hidden form elements or JavaScript that automatically submits requests to the vulnerable plugin endpoints on the target WordPress site. Since the administrator's browser automatically includes their authentication cookies with the request, the WordPress site processes the forged request as legitimate.

A typical attack scenario involves:

1. Attacker identifies a WordPress site running a vulnerable version of Foliopress WYSIWYG
2. Attacker crafts a malicious HTML page containing a hidden form targeting the vulnerable endpoint
3. Attacker entices an authenticated administrator to visit the malicious page
4. The forged request executes, potentially injecting malicious JavaScript (stored XSS)
5. The stored XSS payload then executes for any user visiting the affected page

Detection Methods for CVE-2025-32610

Indicators of Compromise

• Unexpected modifications to WYSIWYG editor settings or content without administrator action
• Presence of unfamiliar JavaScript code in post content, widgets, or plugin settings
• Web server logs showing POST requests to Foliopress WYSIWYG admin endpoints with referrers from external domains
• User reports of suspicious redirects or pop-ups when viewing content edited with the plugin

Detection Strategies

• Audit WordPress plugin versions and flag installations with Foliopress WYSIWYG versions <= 2.6.18
• Monitor web application firewall (WAF) logs for requests to the plugin's administrative endpoints originating from external referrers
• Implement Content Security Policy (CSP) headers and monitor for violations that may indicate XSS execution
• Use WordPress security plugins that scan for known vulnerable plugin versions

Monitoring Recommendations

• Enable detailed logging for WordPress admin actions and plugin configuration changes
• Configure alerts for unexpected bulk content modifications or plugin setting changes
• Regularly review stored content for suspicious script tags or encoded JavaScript payloads
• Monitor for anomalous traffic patterns to WordPress admin endpoints

How to Mitigate CVE-2025-32610

Immediate Actions Required

• Update Foliopress WYSIWYG plugin to the latest patched version available from the WordPress plugin repository
• Audit all content managed through the WYSIWYG editor for signs of injected malicious scripts
• Review WordPress admin activity logs for suspicious configuration changes
• Consider temporarily deactivating the plugin until a patch can be applied if updates are not immediately available

Patch Information

Organizations should monitor the Patchstack Vulnerability Report for updated patch information and remediation guidance. Check the official WordPress plugin repository for the latest secure version of Foliopress WYSIWYG.

Workarounds

• Implement a Web Application Firewall (WAF) with rules to validate referrer headers and block suspicious cross-origin requests to admin endpoints
• Restrict administrative access to WordPress from trusted IP addresses only using .htaccess or server firewall rules
• Enforce strict Content Security Policy headers to mitigate the impact of any injected XSS payloads
• Use browser-based CSRF protection extensions for administrators as an additional defense layer
• Consider switching to an alternative WYSIWYG editor plugin that has been recently audited for security

# Example: Restrict WordPress admin access to specific IPs via .htaccess
# Add to wp-admin/.htaccess
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{REQUEST_URI} ^(.*)?wp-admin.*
RewriteCond %{REMOTE_ADDR} !^192\.168\.1\.100$
RewriteCond %{REMOTE_ADDR} !^10\.0\.0\.50$
RewriteRule ^(.*)$ - [R=403,L]
</IfModule>
