CVE-2025-30522: Contact Form 7 Material Design CSRF Flaw

CVE-2025-30522 Overview

CVE-2025-30522 is a Cross-Site Request Forgery (CSRF) vulnerability in the Contact Form 7 Material Design WordPress plugin developed by Damian Orzol. The flaw affects all versions of cf7-material-design up to and including 1.0.0. An attacker can leverage the CSRF weakness to inject persistent JavaScript payloads, resulting in Stored Cross-Site Scripting (XSS) within the WordPress administrative interface. The vulnerability is tracked under CWE-352 and requires user interaction from an authenticated administrator to succeed.

Critical Impact
A successful attack chains CSRF with Stored XSS, enabling attackers to execute arbitrary scripts in the context of an authenticated WordPress administrator and persist payloads across the site.

Affected Products

Damian Orzol Contact Form 7 Material Design (cf7-material-design) plugin for WordPress
All plugin versions from initial release through 1.0.0
WordPress installations with the affected plugin activated

Technical Details for CVE-2025-30522

Vulnerability Analysis

The vulnerability arises because the cf7-material-design plugin processes state-changing requests without validating an anti-CSRF token. An attacker hosts a malicious page that issues a forged request to a vulnerable plugin endpoint. When an authenticated WordPress administrator visits the attacker-controlled page, the browser automatically attaches valid session cookies to the forged request. The plugin accepts the request and stores attacker-controlled input that is later rendered in the WordPress dashboard without proper output encoding.

The result is a Stored XSS condition with persistent impact. Subsequent visits by privileged users execute the injected JavaScript in their browser session. Attackers can use this to harvest session tokens, create rogue administrator accounts, modify plugin or theme files, or pivot to additional WordPress components.

Root Cause

The root cause is missing CSRF protection on a request handler that accepts persistent input. WordPress provides nonce primitives such as wp_nonce_field() and check_admin_referer() to bind requests to a user session, but the affected plugin code paths do not invoke these checks. The condition is compounded by missing output sanitization, allowing injected markup to execute when rendered.

Attack Vector

Exploitation is remote and requires user interaction. The attack vector is network-based and proceeds in three stages. First, the attacker crafts an HTML page containing an auto-submitting form or hidden image tag that targets the vulnerable plugin endpoint. Second, the attacker lures a logged-in WordPress administrator to the page using phishing, comment links, or watering-hole techniques. Third, the forged request submits a JavaScript payload that the plugin stores. The payload then executes whenever any administrator loads the page that renders the stored data.

The vulnerability spans a scope change because script execution in the administrator context can affect components beyond the vulnerable plugin itself. No prior authentication is required from the attacker, but the targeted victim must be authenticated to WordPress at the time of interaction.

Detection Methods for CVE-2025-30522

Indicators of Compromise

Unexpected <script> tags, event handlers, or inline JavaScript stored in Contact Form 7 Material Design configuration fields or form output
WordPress administrator sessions originating from unfamiliar IP addresses shortly after a known administrator browsed an external link
Newly created administrator accounts or modified user roles without corresponding administrative activity
Outbound HTTP requests from administrator browsers to unknown domains immediately after loading a WordPress admin page

Detection Strategies

Inventory all WordPress sites and identify installations where cf7-material-design is installed at version 1.0.0 or earlier
Inspect the wp_options, wp_postmeta, and plugin-specific tables for stored HTML containing <script>, onerror=, onload=, or javascript: patterns
Review web server access logs for POST requests to plugin endpoints that lack a valid Referer header matching the site origin
Correlate browser telemetry from administrator workstations with WordPress admin page loads to identify unexpected script execution

Monitoring Recommendations

Enable WordPress audit logging to capture option updates, user role changes, and plugin or theme file modifications
Deploy a web application firewall rule that blocks requests to admin endpoints missing valid WordPress nonces
Alert on any administrator account creation or capability elevation outside of approved change windows
Monitor for HTTP responses delivering attacker-controlled JavaScript from WordPress admin URIs

How to Mitigate CVE-2025-30522

Immediate Actions Required

Deactivate and remove the cf7-material-design plugin until a patched version is released and verified
Force a password reset and invalidate active sessions for all WordPress administrator and editor accounts
Audit user accounts, scheduled tasks (wp_cron), and plugin or theme files for unauthorized modifications
Restrict administrator access to trusted IP ranges and require multi-factor authentication for wp-admin

Patch Information

At the time of publication, no fixed version has been identified beyond 1.0.0. Refer to the Patchstack Vulnerability Report for vendor status updates. Replace the plugin with a maintained alternative if a patch remains unavailable.

Workarounds

Remove the plugin entirely and use the upstream Contact Form 7 plugin without the Material Design extension
Apply a virtual patch via a web application firewall that enforces nonce presence on plugin POST handlers
Configure Content Security Policy (CSP) headers to disallow inline scripts in the WordPress admin context
Train administrators to log out of WordPress before browsing untrusted links and to use a dedicated browser profile for admin tasks

bash

# Configuration example - identify and remove the vulnerable plugin via WP-CLI
wp plugin list --name=cf7-material-design --fields=name,status,version
wp plugin deactivate cf7-material-design
wp plugin uninstall cf7-material-design

# Reset sessions for all administrators after suspected exploitation
wp user list --role=administrator --field=ID | xargs -I {} wp user session destroy {} --all
