CVE-2025-47610 Overview
CVE-2025-47610 is a stored Cross-Site Scripting (XSS) vulnerability in the Wetail WooCommerce Fortnox Integration plugin for WordPress. The flaw affects all versions of woocommerce-fortnox-integration up to and including 4.5.6. An authenticated attacker with low privileges can inject persistent JavaScript payloads that execute in the browsers of users who view the affected pages. The issue is tracked under CWE-79: Improper Neutralization of Input During Web Page Generation.
Critical Impact
Attackers with low-privileged accounts can store malicious scripts that execute in administrator sessions, enabling session hijacking, credential theft, and unauthorized WooCommerce store actions.
Affected Products
- Wetail WooCommerce Fortnox Integration plugin for WordPress
- All versions from initial release through 4.5.6
- WordPress sites running WooCommerce with the Fortnox Integration plugin enabled

Technical Details for CVE-2025-47610
Vulnerability Analysis
The WooCommerce Fortnox Integration plugin fails to properly neutralize user-supplied input before rendering it within web page output. This allows attackers to persist arbitrary JavaScript into plugin-controlled fields. When a legitimate user, typically a store administrator, loads the affected page, the browser executes the stored payload in the context of the WordPress origin.
Exploitation requires low-level authentication and user interaction, but the scope changes across security boundaries. A successful attack impacts the confidentiality, integrity, and availability of the WordPress and WooCommerce environment. According to Patchstack, the issue was reported against version 4.5.5 and remains present through 4.5.6.
Root Cause
The root cause is missing or insufficient output encoding on input fields handled by the plugin. Input received from authenticated users is stored in the database and later rendered without HTML-context escaping. Standard WordPress sanitization functions such as esc_html(), esc_attr(), or wp_kses_post() are not applied to the vulnerable sink.
Attack Vector
The attack is delivered over the network by an authenticated user with contributor-level or similar low privileges. The attacker submits a payload containing HTML or JavaScript into a vulnerable plugin field. The payload persists in the WordPress database and executes when an administrator or another user visits the rendering page. Because execution occurs in the origin of the WordPress site, the attacker can perform actions on behalf of the victim, including creating admin accounts, altering Fortnox integration settings, or exfiltrating order data.
No public proof-of-concept exploit code has been released. Refer to the Patchstack Vulnerability Report for additional context.
Detection Methods for CVE-2025-47610
Indicators of Compromise
- Unexpected <script>, <iframe>, or event-handler attributes (such as onerror=, onload=) in plugin-managed database entries or option values.
- New WordPress administrator accounts or role changes that correlate with recent access to Fortnox Integration pages.
- Outbound requests from administrator browsers to unknown domains shortly after loading WooCommerce or Fortnox admin screens.
Detection Strategies
- Audit database tables including wp_options, wp_postmeta, and plugin-specific tables for HTML or JavaScript content in fields that should contain plain text.
- Enable and review WordPress audit logs for changes to plugin settings performed by low-privileged accounts.
- Deploy a Content Security Policy (CSP) in report-only mode to surface inline script executions originating from plugin pages.
Monitoring Recommendations
- Monitor administrator session activity for anomalous API calls to /wp-admin/admin-ajax.php and REST endpoints under /wp-json/.
- Alert on modifications to user roles, capabilities, and the wp_users table originating from authenticated sessions.
- Track outbound HTTP requests from browsers accessing WordPress admin interfaces to identify data exfiltration attempts.
How to Mitigate CVE-2025-47610
Immediate Actions Required
- Identify all WordPress sites running the Wetail WooCommerce Fortnox Integration plugin at version 4.5.6 or earlier.
- Restrict access to the WordPress admin area to trusted IP ranges until a patched version is deployed.
- Review recent activity of low-privileged accounts and rotate credentials for any potentially exposed administrator sessions.
Patch Information
At the time of the latest NVD update, no fixed version has been publicly indexed. Monitor the Patchstack advisory and the vendor's plugin repository for a release beyond 4.5.6 that addresses the input neutralization flaw. Apply the update immediately once available.
Workarounds
- Temporarily disable the WooCommerce Fortnox Integration plugin if Fortnox synchronization is not business-critical.
- Deploy a web application firewall (WAF) rule to block requests containing common XSS payload patterns targeting plugin endpoints.
- Reduce the number of accounts with contributor-level or higher privileges and enforce multi-factor authentication for all WordPress users.
