CVE-2025-31807 Overview
CVE-2025-31807 is a Cross-Site Request Forgery (CSRF) vulnerability in the CloudRedux Product Notices for WooCommerce WordPress plugin. The flaw affects all versions up to and including 1.3.4. The vulnerability is tracked under CWE-352: Cross-Site Request Forgery.
An attacker can craft a malicious web page or link that, when visited by an authenticated administrator, triggers unintended state-changing actions on the WooCommerce store. Exploitation requires user interaction but no privileges on the target site. The issue impacts integrity of plugin-managed settings.
Critical Impact
Authenticated administrators tricked into visiting attacker-controlled content can have plugin configuration modified without consent, altering product notice behavior across the WooCommerce storefront.
Affected Products
- CloudRedux Product Notices for WooCommerce plugin — all versions from n/a through 1.3.4
- WordPress sites running WooCommerce with the product-notices-for-woocommerce plugin installed
- Administrator sessions on affected WordPress installations

Technical Details for CVE-2025-31807
Vulnerability Analysis
The Product Notices for WooCommerce plugin exposes administrative actions that lack sufficient CSRF protection. WordPress provides a nonce mechanism (wp_nonce_field, check_admin_referer) that binds sensitive requests to a specific user session. When plugin endpoints omit or fail to validate these nonces, any authenticated session can be abused across origins.
An attacker hosts a page containing a form or script that submits requests to the target WordPress site. If the victim administrator visits the page while logged in, the browser attaches session cookies and the request executes with admin privileges. The impact is bounded to integrity of plugin settings, with no direct confidentiality or availability effect per the CVSS vector.
Exploitation requires social engineering to lure a privileged user. Attack complexity is low because the request format is predictable from plugin source code available in the WordPress plugin repository.
Root Cause
The root cause is missing or improper validation of anti-CSRF tokens on state-changing HTTP handlers within the plugin. Requests that modify plugin configuration do not verify a nonce tied to the acting user, allowing forged submissions from external origins to succeed.
Attack Vector
The attack vector is network-based and requires user interaction. An attacker sends a crafted link or embeds an auto-submitting form on a page under their control. When an authenticated WordPress administrator loads the resource, the browser issues the forged request to the vulnerable plugin endpoint. The server processes the request under the victim's session context.

Detection Methods for CVE-2025-31807
Indicators of Compromise
- Unexpected modifications to Product Notices for WooCommerce plugin settings in the WordPress admin dashboard
- HTTP POST requests to wp-admin endpoints associated with the plugin containing Referer headers from external domains
- Administrator activity logs showing configuration changes without a corresponding admin UI session
Detection Strategies
- Review WordPress audit logs for plugin option changes correlated with external referrers or unusual timing
- Inspect web server access logs for cross-origin POST requests to plugin admin URLs missing valid _wpnonce parameters
- Deploy a Web Application Firewall (WAF) rule to flag admin-scoped requests lacking a same-origin Referer or a nonce token
Monitoring Recommendations
- Enable WordPress activity logging plugins to capture setting changes with user, IP, and referrer context
- Alert on administrator account actions occurring outside expected working hours or from unusual IP addresses
- Monitor plugin file integrity and configuration snapshots for unauthorized drift
How to Mitigate CVE-2025-31807
Immediate Actions Required
- Update the Product Notices for WooCommerce plugin to a version later than 1.3.4 once a patched release is available from CloudRedux
- Audit administrator accounts and enforce least-privilege role assignments to reduce the blast radius of CSRF
- Require administrators to log out of WordPress sessions before browsing untrusted sites
Patch Information
At time of publication, the vulnerability affects all versions up to and including 1.3.4. Review the Patchstack advisory for the latest patched version and vendor guidance.
Workarounds
- Deactivate and remove the plugin until a fixed version is deployed
- Restrict access to /wp-admin/ by IP allowlist through the web server or WAF
- Enforce two-factor authentication and short session lifetimes for all administrator accounts to limit the exposure window
