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 by Damian Orzol. The flaw affects all versions of the cf7-material-design plugin up to and including 1.0.0. An attacker can chain the CSRF weakness into a Stored Cross-Site Scripting (XSS) attack by tricking an authenticated administrator into submitting a crafted request. Once persisted, the injected script executes in the browser of any user viewing the affected page.

Critical Impact

Successful exploitation enables Stored XSS in a WordPress administrative context, allowing session theft, content manipulation, and pivoting to further site compromise.

Affected Products

• Contact Form 7 Material Design plugin (cf7-material-design) for WordPress
• All versions from initial release through 1.0.0
• WordPress sites running the plugin with authenticated administrator sessions

Technical Details for CVE-2025-30522

Vulnerability Analysis

The vulnerability combines two weaknesses into one exploitation chain. The plugin fails to validate the origin of state-changing requests, which is the CSRF condition tracked as [CWE-352]. The same request handler also fails to sanitize or encode user-supplied input before storing it, allowing arbitrary script content to be saved in the WordPress database. When an administrator visits an attacker-controlled page while authenticated to WordPress, the browser silently submits the malicious request using the administrator's session cookie. The plugin processes the forged request as legitimate and persists the attacker's payload.

The stored payload executes whenever a user loads the affected plugin output, producing a Stored XSS condition. Because the entry point is a CSRF, the attacker does not need credentials and only requires the target to visit a malicious URL.

Root Cause

The root cause is missing CSRF protection on plugin form-handling endpoints. WordPress provides nonce primitives such as wp_nonce_field() and check_admin_referer() that the plugin does not enforce on the vulnerable action. The absence of these checks lets external sites submit valid administrative requests. A secondary defect is the lack of output encoding or input sanitization using functions such as sanitize_text_field() or wp_kses(), which permits script payloads to be stored verbatim.

Attack Vector

The attack is network-based and requires user interaction. An attacker hosts a page containing an auto-submitting HTML form or JavaScript request targeting the vulnerable plugin endpoint. When an authenticated WordPress administrator visits the page, their browser sends the request with valid session cookies. The plugin saves the attacker-supplied JavaScript, which then executes in every subsequent administrator or visitor session that loads the affected output. The scope changes between components, increasing the blast radius beyond the originally vulnerable plugin.

The vulnerability is described in prose because no proof-of-concept code has been published. See the Patchstack Vulnerability Report for additional technical details.

Detection Methods for CVE-2025-30522

Indicators of Compromise

• Unexpected <script>, onerror=, or onload= content stored in plugin-managed WordPress options or post metadata
• POST requests to cf7-material-design plugin endpoints with a Referer header pointing to an external domain
• Administrator browser sessions executing JavaScript that initiates outbound requests to unfamiliar hosts
• New or modified WordPress administrative users created shortly after an administrator visited an external link

Detection Strategies

• Inspect the WordPress wp_options and plugin-specific tables for HTML or JavaScript tokens in fields expected to contain plain text
• Review web server access logs for state-changing POST requests to plugin paths lacking a same-origin Referer
• Deploy a Content Security Policy in report-only mode to surface inline script execution in administrative pages

Monitoring Recommendations

• Enable WordPress audit logging to record plugin settings changes and capture the originating IP and user
• Alert on administrator account activity that occurs immediately after rendering pages containing the plugin output
• Monitor for outbound requests from administrator browsers to domains not associated with the WordPress installation

How to Mitigate CVE-2025-30522

Immediate Actions Required

• Deactivate the Contact Form 7 Material Design plugin until a patched version is confirmed available from the maintainer
• Audit existing plugin data for stored JavaScript payloads and remove any unauthorized entries
• Force re-authentication of all WordPress administrators and rotate any credentials that may have been exposed through administrative sessions

Patch Information

At the time of publication, no fixed version is listed beyond 1.0.0 in the advisory. Site operators should monitor the Patchstack Vulnerability Report and the WordPress plugin repository for an updated release that adds nonce verification and input sanitization.

Workarounds

• Remove the cf7-material-design plugin directory from wp-content/plugins/ if a maintained alternative is available
• Restrict access to /wp-admin/ using IP allow-lists or HTTP authentication to reduce CSRF exposure for administrators
• Deploy a web application firewall rule that blocks cross-origin POST requests to plugin endpoints lacking a valid WordPress nonce
• Apply a strict Content Security Policy that disallows inline scripts on administrative pages

# Disable the vulnerable plugin from the command line
wp plugin deactivate cf7-material-design --allow-root
wp plugin delete cf7-material-design --allow-root
