CVE-2025-64226: Stockie Extra CSRF Vulnerability

CVE-2025-64226 Overview

CVE-2025-64226 is a Cross-Site Request Forgery (CSRF) vulnerability [CWE-352] affecting the colabrio Stockie Extra WordPress plugin. The flaw impacts all versions of stockie-extra up to and including 1.2.11. An attacker can craft a malicious web page that, when visited by an authenticated user, triggers unintended state-changing actions in the plugin. Exploitation requires user interaction but no privileges on the target application. The vulnerability affects integrity with limited impact and does not directly expose confidential data or degrade availability.

Critical Impact
Attackers can force authenticated WordPress users to perform unintended plugin actions by luring them to a malicious page.

Affected Products

colabrio Stockie Extra WordPress plugin (stockie-extra)
All versions from initial release through 1.2.11
WordPress sites where the plugin is installed and active

Technical Details for CVE-2025-64226

Vulnerability Analysis

The vulnerability stems from missing or insufficient CSRF protection in the Stockie Extra plugin. Sensitive state-changing endpoints do not properly validate a WordPress nonce or verify the origin of incoming requests. An attacker who can convince an authenticated WordPress user to click a link or load a crafted page can cause the browser to submit forged requests to the target site. Because browsers automatically attach session cookies, the plugin processes these requests as if they came from the legitimate user.

The attack vector is network-based and requires user interaction, but no attacker authentication is needed. The scope remains unchanged, and the impact is limited to partial integrity loss. Confidentiality and availability are not directly affected.

Root Cause

The root cause is a missing anti-CSRF token check on one or more request handlers within the stockie-extra plugin. WordPress provides built-in mechanisms such as wp_nonce_field() and check_admin_referer() to protect against CSRF, but the vulnerable handlers do not enforce these checks before processing requests.

Attack Vector

An attacker hosts a malicious page containing an auto-submitting form or image tag that targets a vulnerable plugin endpoint on the victim's WordPress site. When an authenticated administrator or user visits the page, the browser silently issues the request using their session. The plugin executes the action, resulting in unauthorized configuration changes or data modification within the plugin scope.

See the Patchstack Vulnerability Report for additional technical details.

Detection Methods for CVE-2025-64226

Indicators of Compromise

Unexpected changes to Stockie Extra plugin settings without corresponding administrator activity in audit logs.
HTTP POST requests to plugin endpoints with Referer headers pointing to external, untrusted domains.
Authenticated requests to plugin admin actions lacking a valid WordPress nonce parameter (_wpnonce).

Detection Strategies

Review WordPress access logs for requests to stockie-extra endpoints originating from cross-origin referrers.
Correlate plugin configuration changes with authenticated user session activity to identify anomalies.
Deploy a web application firewall (WAF) rule to flag state-changing requests missing valid _wpnonce tokens.

Monitoring Recommendations

Enable WordPress audit logging plugins to track administrative actions and configuration changes.
Monitor for unusual outbound links or scripts embedded in comments, posts, or third-party content that could target logged-in users.
Alert on HTTP 302 redirects following plugin admin actions initiated from external referrers.

How to Mitigate CVE-2025-64226

Immediate Actions Required

Identify all WordPress sites running the stockie-extra plugin at version 1.2.11 or earlier.
Deactivate the plugin if a patched version is not yet available and the functionality is not business-critical.
Require administrators to log out of WordPress sessions before browsing untrusted content.

Patch Information

No fixed version is listed in the available advisory. The vulnerability affects Stockie Extra through version 1.2.11. Site owners should monitor the Patchstack Vulnerability Report and the vendor for a security update, and apply it as soon as it is released.

Workarounds

Restrict access to the WordPress admin interface using IP allowlists at the web server or WAF layer.
Enforce SameSite=Strict or SameSite=Lax cookie attributes on the WordPress session cookie to reduce CSRF exposure.
Use a WAF ruleset that blocks state-changing requests to wp-admin endpoints when the Referer header is missing or cross-origin.

bash

# Example nginx configuration to block cross-origin POST requests to wp-admin
location ~* /wp-admin/ {
    if ($request_method = POST) {
        set $block_csrf 0;
        if ($http_referer !~* "^https?://your-site\.example\.com") {
            set $block_csrf 1;
        }
        if ($block_csrf = 1) {
            return 403;
        }
    }
