CVE-2025-24699: WP Coder CSRF Vulnerability

CVE-2025-24699 is a Cross-Site Request Forgery vulnerability in the WP Coder WordPress plugin that enables XSS attacks. This vulnerability affects versions up to 3.6. This article covers technical details, impact, and mitigation.

Published: April 22, 2026

CVE-2025-24699 Overview

CVE-2025-24699 is a Cross-Site Request Forgery (CSRF) vulnerability in the WP Coder plugin by Wow-Company that enables Cross-Site Scripting (XSS) attacks. This chained vulnerability allows attackers to trick authenticated administrators into executing malicious actions, ultimately leading to the injection and execution of arbitrary JavaScript code within the WordPress admin context.

Critical Impact

Attackers can leverage CSRF to inject persistent XSS payloads, potentially compromising WordPress administrator sessions, stealing credentials, or gaining complete control over affected WordPress installations.

Affected Products

  • WP Coder WordPress Plugin versions through 3.6
  • WordPress installations using vulnerable WP Coder versions
  • Websites with wp-coder plugin installed without CSRF token validation

Technical Details for CVE-2025-24699

Vulnerability Analysis

This vulnerability represents a dangerous attack chain where Cross-Site Request Forgery (CSRF) is exploited to achieve Cross-Site Scripting (XSS). The WP Coder plugin, which allows users to add custom code snippets to WordPress sites, fails to properly validate request origins on critical administrative functions. This missing CSRF protection enables attackers to craft malicious requests that, when executed by an authenticated administrator, inject JavaScript code into the plugin's stored configurations.

The CSRF-to-XSS attack chain is particularly dangerous because it combines two distinct vulnerability classes. The CSRF component bypasses same-origin policies by exploiting the trust relationship between the browser and the vulnerable application. Once the malicious request is processed, the XSS payload becomes persistent within the WordPress database, executing every time the affected page or admin section is loaded.

Root Cause

The root cause of this vulnerability is the absence of proper nonce verification (WordPress's CSRF protection mechanism) in the WP Coder plugin's administrative endpoints. WordPress provides built-in functions like wp_nonce_field() and wp_verify_nonce() specifically for CSRF protection, but the plugin failed to implement these security controls on form submissions and AJAX handlers that process user-supplied code content.

Additionally, the plugin lacks adequate output encoding when rendering stored code snippets in the administrative interface, allowing injected JavaScript to execute in the context of administrative sessions.

Attack Vector

The attack requires social engineering to convince an authenticated WordPress administrator to visit a malicious webpage or click a crafted link while logged into their WordPress dashboard. The attacker prepares a webpage containing a hidden form that automatically submits a POST request to the vulnerable WP Coder endpoint.

When the administrator visits the attacker's page, the hidden form submits without interaction, carrying the administrator's session cookies. The vulnerable endpoint processes the request as legitimate, storing the attacker's malicious JavaScript payload. Subsequent visits to the affected WordPress admin pages trigger the stored XSS, potentially exfiltrating session tokens, creating rogue admin accounts, or further compromising the installation.

The attack can be delivered through phishing emails, malicious advertisements, or compromised websites that target WordPress administrators. No authentication is required from the attacker's perspective—they simply need to lure an authenticated victim to their malicious page.

Detection Methods for CVE-2025-24699

Indicators of Compromise

  • Unexpected JavaScript code or <script> tags appearing in WP Coder plugin configurations
  • Unauthorized administrative actions in WordPress audit logs without corresponding admin activity
  • Presence of new administrator accounts that were not legitimately created
  • Suspicious iframe or form elements in plugin settings pointing to external domains

Detection Strategies

  • Monitor WordPress database tables associated with WP Coder for unauthorized modifications to stored code snippets
  • Implement Web Application Firewall (WAF) rules to detect and block CSRF attack patterns targeting WordPress plugins
  • Review server access logs for suspicious POST requests to WP Coder admin endpoints from external referrers
  • Deploy content security policy (CSP) headers to detect and report inline script execution anomalies

Monitoring Recommendations

  • Enable WordPress audit logging to track all administrative actions and plugin configuration changes
  • Configure alerting for any modifications to the wp_coder database tables outside of normal administrative workflows
  • Monitor for outbound connections from the WordPress admin interface to unknown external domains
  • Implement SentinelOne's WordPress protection capabilities to detect post-exploitation activities and suspicious script execution

How to Mitigate CVE-2025-24699

Immediate Actions Required

  • Update WP Coder plugin to a patched version (newer than 3.6) as soon as one becomes available
  • Audit existing WP Coder configurations for any suspicious or unauthorized code injections
  • Implement additional CSRF protection at the web server or WAF level for WordPress admin endpoints
  • Consider temporarily deactivating WP Coder if it is not critical to site operations until a patch is released

Patch Information

The vulnerability affects WP Coder versions through 3.6. Users should monitor the Patchstack WordPress Vulnerability Report for updates on patch availability. Once a patched version is released, upgrade immediately through the WordPress admin dashboard or via WP-CLI using wp plugin update wp-coder.

Workarounds

  • Implement a Web Application Firewall (WAF) rule to validate referrer headers and block cross-origin POST requests to WordPress admin endpoints
  • Add custom CSRF validation using WordPress hooks by implementing admin_init checks for proper nonce verification on WP Coder requests
  • Restrict access to the WordPress admin panel by IP address to limit the attack surface
  • Use browser extensions or security headers that prevent automatic form submissions from external sites
bash
# Configuration example - Restrict WordPress admin access by IP in .htaccess
<Files wp-login.php>
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from YOUR.TRUSTED.IP.ADDRESS
</Files>

<Directory /var/www/html/wp-admin>
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from YOUR.TRUSTED.IP.ADDRESS
</Directory>
