CVE-2025-47451: WooCommerce Quantity Dropdown CSRF Flaw

CVE-2025-47451 Overview

CVE-2025-47451 is a Cross-Site Request Forgery (CSRF) vulnerability in the Product Quantity Dropdown For Woocommerce WordPress plugin developed by silverplugins217. The flaw affects all plugin versions up to and including 1.2. An attacker can trick an authenticated administrator into submitting a forged request that changes plugin settings without consent. Exploitation requires user interaction, typically achieved by luring a logged-in administrator to a malicious page. The vulnerability is tracked under CWE-352: Cross-Site Request Forgery.

Critical Impact
A successful attack allows unauthorized modification of plugin settings on the target WooCommerce store, potentially disrupting product quantity configurations and store operations.

Technical Details for CVE-2025-47451

Vulnerability Analysis

The Product Quantity Dropdown For Woocommerce plugin fails to validate the authenticity of state-changing HTTP requests. Administrative actions that update plugin settings lack proper CSRF tokens or nonce verification. This allows attackers to craft malicious HTML pages that submit forged POST requests to the plugin's settings endpoints. When an authenticated administrator visits the attacker-controlled page, the browser automatically includes valid session cookies. The forged request executes with the administrator's privileges, modifying plugin configuration without explicit consent.

Root Cause

The vulnerability stems from missing CSRF protection mechanisms in the plugin's settings handlers. WordPress provides built-in wp_nonce_field() and check_admin_referer() functions specifically for this purpose. The affected plugin versions do not implement these standard defenses on settings update endpoints. The absence of anti-CSRF tokens allows any cross-origin request to succeed if the target user has an active administrative session.

Attack Vector

Exploitation follows a classic CSRF pattern. An attacker hosts a malicious page containing an auto-submitting form or JavaScript payload targeting the vulnerable plugin's settings URL. The attacker delivers this page through phishing emails, forum posts, or compromised websites. When a WordPress administrator with the plugin installed visits the page while logged in, the browser sends the forged request with valid authentication cookies. The plugin processes the request as legitimate and applies the attacker-controlled settings changes. See the Patchstack advisory for technical details.

Detection Methods for CVE-2025-47451

Indicators of Compromise

Unexpected changes to Product Quantity Dropdown plugin settings in wp-admin
HTTP POST requests to plugin settings endpoints with Referer headers pointing to external domains
Administrator account activity from unusual browser sessions or IP addresses
WordPress audit log entries showing settings modifications without corresponding admin panel navigation

Detection Strategies

Monitor WordPress access logs for POST requests to the plugin's admin endpoints with mismatched or missing Referer headers
Deploy web application firewall (WAF) rules that inspect Origin and Referer headers on administrative requests
Enable WordPress audit logging plugins to record all settings changes with timestamps and source IPs
Correlate administrator browser sessions with settings modification events to identify anomalies

Monitoring Recommendations

Alert on plugin configuration changes occurring outside expected maintenance windows
Track administrator user agents and IP addresses for behavioral baselines
Review outbound email and browser proxy logs for links delivered to WordPress administrators
Establish alerting for any WooCommerce plugin settings modifications performed without prior admin panel authentication events

How to Mitigate CVE-2025-47451

Immediate Actions Required

Deactivate the Product Quantity Dropdown For Woocommerce plugin until a patched version is released
Audit current plugin settings for unauthorized modifications and restore known-good values
Force logout of all WordPress administrators and require password resets
Restrict wp-admin access to trusted IP addresses through server-level ACLs or .htaccess rules

Patch Information

At the time of publication, no fixed version has been identified in the NVD record. Vulnerable versions include all releases through 1.2. Monitor the Patchstack database entry and the WordPress plugin repository for updates from the vendor.

Workarounds

Remove or deactivate the vulnerable plugin until the vendor releases a patched version
Deploy a WAF rule that enforces SameSite=Strict cookie policies for WordPress admin sessions
Require administrators to use separate browsers or browser profiles exclusively for wp-admin activities
Implement two-factor authentication (2FA) on all administrator accounts to raise the bar for account misuse

bash

# Example WAF rule to block cross-origin POST requests to wp-admin
# ModSecurity rule enforcing Referer header validation
SecRule REQUEST_METHOD "@streq POST" \
    "chain,phase:1,deny,status:403,id:1000001,\
    msg:'Blocked cross-origin POST to wp-admin'"
SecRule REQUEST_URI "@contains /wp-admin/" "chain"
SecRule REQUEST_HEADERS:Referer "!@beginsWith https://your-site.example.com"
