CVE-2025-47491: Contact Form Widget CSRF Vulnerability

CVE-2025-47491 Overview

CVE-2025-47491 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Contact Form Widget plugin (new-contact-form-widget) developed by A WP Life for WordPress. This vulnerability allows attackers to perform unauthorized actions on behalf of authenticated users by tricking them into visiting a malicious webpage while logged into their WordPress site.

Critical Impact

Attackers can exploit this CSRF vulnerability to execute unauthorized administrative actions on WordPress sites running vulnerable versions of the Contact Form Widget plugin, potentially leading to configuration changes, data manipulation, or further compromise.

Affected Products

• Contact Form Widget (new-contact-form-widget) versions through 1.4.6
• WordPress installations using the vulnerable plugin versions

Technical Details for CVE-2025-47491

Vulnerability Analysis

This Cross-Site Request Forgery (CSRF) vulnerability exists in the Contact Form Widget plugin for WordPress. CSRF attacks exploit the trust that a web application has in an authenticated user's browser. When a WordPress administrator with an active session visits a malicious page crafted by an attacker, the attacker can force the victim's browser to make requests to the WordPress site that perform actions without the user's knowledge or consent.

The vulnerability stems from insufficient validation of request origins in the plugin's form handling mechanisms. The Contact Form Widget plugin fails to properly implement anti-CSRF tokens (nonces) to verify that requests originate from legitimate user interactions within the WordPress admin interface.

Root Cause

The root cause is the absence or improper implementation of WordPress nonce verification in the plugin's action handlers. WordPress provides built-in CSRF protection through its nonce system (wp_nonce_field() and wp_verify_nonce()), but these protections are not adequately utilized in the affected versions of the Contact Form Widget plugin. This allows state-changing requests to be processed without verifying that they were intentionally initiated by the authenticated user.

Attack Vector

An attacker exploits this vulnerability by crafting a malicious HTML page containing hidden form elements or JavaScript that automatically submits requests to the vulnerable WordPress plugin endpoints. The attack flow typically proceeds as follows:

1. The attacker identifies a WordPress site running Contact Form Widget version 1.4.6 or earlier
2. The attacker creates a malicious webpage containing requests that target the vulnerable plugin endpoints
3. The attacker lures an authenticated WordPress administrator to visit the malicious page
4. The victim's browser automatically sends the forged requests with valid session cookies
5. The WordPress site processes the requests as if they were legitimate administrative actions

The vulnerability does not require prior authentication by the attacker, as it leverages the victim's existing authenticated session. For more technical details, refer to the Patchstack Vulnerability Report.

Detection Methods for CVE-2025-47491

Indicators of Compromise

• Unexpected changes to Contact Form Widget plugin settings without administrator action
• Unusual HTTP POST requests to WordPress admin endpoints originating from external referrers
• Audit log entries showing administrative actions that administrators do not recall performing
• Modifications to form configurations or widget settings at times when no administrators were active

Detection Strategies

• Implement WordPress audit logging plugins to track all administrative changes and their origins
• Monitor HTTP referrer headers for requests to plugin endpoints to detect external referrers
• Configure web application firewalls (WAF) to detect and block requests with suspicious cross-origin patterns
• Review server access logs for unusual POST requests to /wp-admin/ endpoints from external sources

Monitoring Recommendations

• Enable comprehensive logging for all WordPress administrative actions including plugin configuration changes
• Set up alerts for configuration modifications to the Contact Form Widget plugin outside of normal maintenance windows
• Regularly review user session activity and correlate with expected administrative operations
• Implement real-time monitoring for requests that lack valid WordPress nonces

How to Mitigate CVE-2025-47491

Immediate Actions Required

• Update the Contact Form Widget plugin to a patched version (if available) that addresses the CSRF vulnerability
• Consider temporarily deactivating the Contact Form Widget plugin until a patch is applied
• Educate WordPress administrators about the risks of clicking unknown links while logged into the admin panel
• Implement a web application firewall with CSRF protection rules as an additional defense layer

Patch Information

Administrators should check the WordPress plugin repository for updated versions of the Contact Form Widget plugin that address this CSRF vulnerability. Detailed patch information is available through the Patchstack Vulnerability Report.

Workarounds

• Restrict administrative access to trusted IP addresses using .htaccess or server-level firewall rules
• Log out of WordPress administrator sessions when not actively performing administrative tasks
• Use browser profiles or separate browsers for administrative activities versus general browsing
• Implement additional CSRF protection at the web server level using security headers and WAF rules
