CVE-2025-47446: Listamester Plugin CSRF Vulnerability

CVE-2025-47446 Overview

CVE-2025-47446 is a Cross-Site Request Forgery (CSRF) vulnerability in the Listamester WordPress plugin. The flaw affects all versions of Listamester up to and including 2.3.6. An attacker can trick an authenticated user into submitting a forged request that performs unintended state-changing actions within the plugin. The vulnerability is classified under [CWE-352] and requires user interaction to succeed. Exploitation occurs over the network without authentication on the attacker's side.

Critical Impact
A successful attack can cause limited integrity impact within the Listamester plugin by executing unauthorized actions on behalf of a logged-in WordPress user.

Affected Products

Listamester WordPress plugin versions up to and including 2.3.6
WordPress sites with Listamester installed and active
Any deployment where administrators or privileged users access the WordPress dashboard while browsing external sites

Technical Details for CVE-2025-47446

Vulnerability Analysis

The vulnerability stems from missing or insufficient CSRF protections in the Listamester plugin. WordPress plugins are expected to validate requests using nonces or equivalent anti-CSRF tokens before performing state-changing operations. Listamester does not adequately verify request origin, allowing forged requests to be processed as legitimate. An attacker crafts a malicious page or link containing a request targeted at a vulnerable Listamester endpoint. When an authenticated WordPress user visits the attacker-controlled resource, the browser silently submits the forged request with the victim's session cookies attached. The plugin processes the request as if it originated from the user. Because the CVSS vector indicates limited integrity impact and no confidentiality or availability impact, the attack surface is scoped to unauthorized modifications within the plugin's functionality.

Root Cause

The root cause is the absence of proper request origin validation, categorized as [CWE-352] Cross-Site Request Forgery. The plugin does not consistently enforce WordPress nonce checks using wp_verify_nonce() or check_admin_referer() on sensitive endpoints. Without these verifications, the plugin cannot distinguish between legitimate user-initiated actions and forged requests originating from third-party sites.

Attack Vector

Exploitation requires the victim to be authenticated to the target WordPress site and to interact with attacker-controlled content. An attacker hosts a crafted HTML page containing an auto-submitting form or image tag pointing to a Listamester action endpoint. The victim's browser transmits the request along with valid session cookies. The plugin then executes the requested operation without validating a CSRF token. See the Patchstack WordPress Vulnerability Report for additional technical context.

Detection Methods for CVE-2025-47446

Indicators of Compromise

Unexpected changes to Listamester plugin configuration or data records that do not correlate with legitimate administrator activity
Web server access logs showing POST requests to Listamester endpoints with Referer headers pointing to external, untrusted domains
WordPress audit logs indicating state-changing actions initiated shortly after users clicked external links or opened untrusted email content

Detection Strategies

Monitor WordPress request logs for missing or invalid _wpnonce parameters on Listamester administrative actions
Correlate browser referrer data against expected WordPress admin URLs to identify cross-origin requests targeting the plugin
Deploy a Web Application Firewall (WAF) ruleset that inspects requests to plugin endpoints and flags those lacking valid anti-CSRF tokens

Monitoring Recommendations

Enable a WordPress audit logging plugin to record all administrative actions and configuration changes performed through Listamester
Alert on anomalous administrative activity outside normal working hours or from unusual geographic IP addresses
Review web server logs for repeated POST requests to plugin endpoints originating from unfamiliar Referer values

How to Mitigate CVE-2025-47446

Immediate Actions Required

Update the Listamester plugin to a version above 2.3.6 once a patched release is available from the vendor
Deactivate and remove the Listamester plugin if a patched version has not been published and the functionality is not essential
Instruct administrators to log out of the WordPress dashboard when not actively managing the site to reduce session exposure

Patch Information

Refer to the Patchstack WordPress Vulnerability Report for the latest patch status. At the time of publication, the vulnerability affects all versions through 2.3.6. Administrators should monitor the WordPress plugin repository and vendor advisories for a fixed release.

Workarounds

Deploy a WAF rule that enforces the presence of a valid _wpnonce parameter on all Listamester administrative POST requests
Restrict access to the WordPress /wp-admin/ directory by source IP address using web server configuration
Require administrators to use a dedicated browser or browser profile for WordPress management to isolate authenticated sessions from general browsing

bash

# Example nginx configuration to restrict wp-admin access by IP
location ~ ^/wp-admin/ {
    allow 203.0.113.0/24;
    deny all;
    include fastcgi_params;
    fastcgi_pass unix:/var/run/php-fpm.sock;
}
