CVE-2025-32667 Overview
CVE-2025-32667 is a Cross-Site Request Forgery (CSRF) vulnerability in the Doppler Forms WordPress plugin developed by fromdoppler. The flaw allows an attacker to trick an authenticated administrator into submitting a forged request that injects persistent JavaScript into plugin-managed content, resulting in Stored Cross-Site Scripting (XSS). The issue affects all versions of doppler-form up to and including 2.5.1. The vulnerability is tracked under CWE-352: Cross-Site Request Forgery and requires user interaction to succeed.
Critical Impact
A successful attack stores attacker-controlled JavaScript that executes in the browsers of site visitors and administrators, enabling session theft, account takeover, and arbitrary actions in the WordPress admin context.
Affected Products
- fromdoppler Doppler Forms (doppler-form) plugin for WordPress
- All versions from initial release through 2.5.1
- WordPress sites running the affected plugin with administrator sessions active

Technical Details for CVE-2025-32667
Vulnerability Analysis
The Doppler Forms plugin exposes state-changing administrative endpoints without adequate CSRF protection. Endpoints that accept form configuration data fail to validate a WordPress nonce or verify the request origin. An attacker who lures an authenticated administrator to a malicious page can issue cross-origin requests that the browser executes with the victim's authenticated session.
Because the same endpoints store user-supplied input without sufficient output encoding or sanitization, the forged request plants a persistent payload. The payload then executes whenever a user renders the affected admin or front-end view, chaining CSRF into Stored XSS. The combined attack widens impact from a single forged action to ongoing script execution against every visitor.
Root Cause
The root cause is the absence of nonce validation on privileged actions, as classified under CWE-352. Plugin handlers do not call check_admin_referer() or wp_verify_nonce() before processing input. Compounding this, the stored input is rendered without escaping through functions such as esc_html() or esc_attr(), allowing HTML and script content to persist in plugin storage.
Attack Vector
Exploitation requires an attacker to host a crafted page or send a malicious link to a logged-in WordPress administrator. When the administrator visits the page, the browser submits a forged POST request to the vulnerable Doppler Forms endpoint, carrying attacker-controlled form fields. The server accepts the request, persists the payload, and serves it back as part of the plugin's rendered output, where it executes in the context of the WordPress site origin.
No valid code example is publicly verified for this issue. See the Patchstack Vulnerability Report for additional technical context.
Detection Methods for CVE-2025-32667
Indicators of Compromise
- Unexpected <script>, onerror, or onload attributes appearing in Doppler Forms configuration records or rendered form markup.
- WordPress access logs showing POST requests to Doppler Forms admin endpoints originating from external Referer headers.
- New or modified administrator accounts created shortly after an admin session interacted with an untrusted external site.
Detection Strategies
- Inspect the database tables and options used by the doppler-form plugin for HTML or JavaScript content in fields expected to hold plain text.
- Review web server logs for state-changing requests to plugin endpoints lacking the standard _wpnonce parameter.
- Deploy a Web Application Firewall (WAF) rule that flags cross-origin POST submissions to /wp-admin/ endpoints associated with the plugin.
Monitoring Recommendations
- Enable WordPress audit logging to capture plugin setting changes and correlate them with administrator session activity.
- Monitor outbound DNS and HTTP requests from administrator browsers for beacons that may indicate active XSS payloads.
- Alert on changes to plugin-managed content outside of approved maintenance windows.
How to Mitigate CVE-2025-32667
Immediate Actions Required
- Identify all WordPress sites running doppler-form and confirm the installed version against 2.5.1.
- Update the Doppler Forms plugin to a version released after 2.5.1 that addresses CVE-2025-32667.
- Force administrator session invalidation and reset credentials if exploitation is suspected.
- Audit plugin-stored data and remove any injected script content before restoring service.
Patch Information
At publication, the vulnerability affects Doppler Forms through 2.5.1. Site operators should consult the Patchstack Vulnerability Report and the WordPress plugin repository for the fixed release and apply it across all environments.
Workarounds
- Deactivate and remove the Doppler Forms plugin until a patched version is deployed.
- Restrict WordPress administrator access to dedicated browsers or sessions that do not browse untrusted sites.
- Apply WAF rules that enforce Referer and Origin header validation on /wp-admin/admin-ajax.php and /wp-admin/admin-post.php requests targeting the plugin.
- Implement a strict Content Security Policy (CSP) that blocks inline script execution to limit Stored XSS impact.
# Example: locate vulnerable installations and disable the plugin via WP-CLI
wp plugin list --name=doppler-form --fields=name,status,version
wp plugin deactivate doppler-form
wp plugin delete doppler-form
