CVE-2025-32113: Libro de Reclamaciones CSRF Vulnerability

CVE-2025-32113 Overview

A Cross-Site Request Forgery (CSRF) vulnerability has been identified in the Libro de Reclamaciones y Quejas WordPress plugin developed by Renzo Tejada. This vulnerability allows attackers to trick authenticated users into performing unintended actions by submitting malicious requests on their behalf. According to the Patchstack advisory, this CSRF vulnerability can be chained with a Stored XSS attack, significantly amplifying the potential impact.

Critical Impact

Attackers can exploit this CSRF vulnerability to perform unauthorized actions in the context of authenticated users, potentially leading to stored cross-site scripting attacks that could compromise administrative accounts and site integrity.

Affected Products

• Libro de Reclamaciones y Quejas WordPress Plugin version 1.0 and earlier
• Libro de Reclamaciones y Quejas WordPress Plugin version 0.9 and earlier
• All versions from initial release through version 1.0

Technical Details for CVE-2025-32113

Vulnerability Analysis

This vulnerability is classified as CWE-352 (Cross-Site Request Forgery). The Libro de Reclamaciones y Quejas plugin, which provides a complaints and claims book functionality for WordPress sites (commonly used for regulatory compliance in Latin American markets), fails to properly implement anti-CSRF protections on critical state-changing operations.

The absence of proper CSRF token validation allows attackers to craft malicious web pages or emails containing forged requests. When an authenticated administrator or user visits the attacker-controlled page, their browser automatically includes session credentials with the forged request, causing the vulnerable plugin to process the action as if it were legitimately initiated by the user.

The chained nature of this vulnerability with stored XSS makes it particularly dangerous, as successful exploitation could result in persistent malicious scripts being injected into the WordPress installation.

Root Cause

The root cause of this vulnerability is the failure to implement proper CSRF protection mechanisms within the plugin's form handling and AJAX request processing. WordPress provides built-in nonce functions (wp_nonce_field(), wp_verify_nonce(), check_admin_referer()) specifically designed to prevent CSRF attacks, but the vulnerable versions of this plugin do not properly utilize these security controls.

State-changing operations within the plugin accept requests without verifying the presence and validity of WordPress nonces, allowing forged cross-origin requests to be processed.

Attack Vector

The attack requires social engineering to lure an authenticated user (typically an administrator) to visit a malicious webpage. The attacker creates an HTML page containing a hidden form or JavaScript that automatically submits a request to the vulnerable plugin endpoint. When the victim visits this page while logged into their WordPress site, the forged request executes with the victim's privileges.

The attack flow typically follows this pattern: an attacker identifies the vulnerable endpoint, crafts a malicious page with a forged form submission, distributes the link via phishing or other social engineering tactics, and when a logged-in admin clicks the link, the unauthorized action is executed. Combined with the stored XSS component, this can lead to persistent site compromise.

Detection Methods for CVE-2025-32113

Indicators of Compromise

• Unexpected changes to plugin settings or stored content in the complaints book
• New or modified entries in the database tables associated with the plugin that weren't created by legitimate users
• Unusual administrative actions logged in WordPress audit logs coinciding with times the administrator may have clicked suspicious links
• Presence of stored XSS payloads or suspicious JavaScript in plugin-managed content areas

Detection Strategies

• Monitor WordPress activity logs for administrative actions performed through the Libro de Reclamaciones y Quejas plugin
• Implement Content Security Policy (CSP) headers to detect and block unauthorized script execution
• Review HTTP request logs for requests to plugin endpoints originating from external referrer URLs
• Deploy web application firewalls (WAF) configured to detect CSRF attack patterns and missing nonce tokens

Monitoring Recommendations

• Enable comprehensive logging for all WordPress administrative actions using security audit plugins
• Configure alerts for any modifications to plugin settings or stored content made outside of normal administrative workflows
• Implement referrer header checking at the web server or WAF level to flag cross-origin requests to sensitive endpoints
• Regularly scan stored content for XSS payloads using automated security scanning tools

How to Mitigate CVE-2025-32113

Immediate Actions Required

• Verify if the Libro de Reclamaciones y Quejas plugin is installed on your WordPress site and check the current version
• If running version 1.0 or earlier, consider temporarily deactivating the plugin until a patched version is available
• Review WordPress audit logs for any suspicious activity that may indicate prior exploitation
• Implement additional access controls and two-factor authentication for WordPress administrative accounts

Patch Information

As of the CVE publication date, no official patch has been confirmed in the available vulnerability data. Site administrators should monitor the Patchstack advisory and the WordPress plugin repository for updated versions of the Libro de Reclamaciones y Quejas plugin. Contact the plugin developer, Renzo Tejada, for information on remediation timelines.

Workarounds

• Deactivate and remove the plugin if it is not essential for business operations until a patched version is released
• Implement a Web Application Firewall (WAF) rule to enforce referrer checking and block suspicious cross-origin requests to the plugin endpoints
• Restrict administrative access to the WordPress dashboard to trusted IP addresses only
• Train administrators to recognize phishing attempts and avoid clicking suspicious links while logged into WordPress

# Configuration example - Apache .htaccess rule to restrict admin access by IP
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/wp-admin [NC]
RewriteCond %{REMOTE_ADDR} !^192\.168\.1\.100$
RewriteCond %{REMOTE_ADDR} !^10\.0\.0\.50$
RewriteRule .* - [F,L]
</IfModule>
