CVE-2025-47661: WordPress SimplePay CSRF Vulnerability

CVE-2025-47661 Overview

CVE-2025-47661 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the codemstory pgall-for-woocommerce WordPress plugin, also known as 워드프레스 결제 심플페이 (WordPress Payment SimplePay). The flaw is tracked under [CWE-352] and impacts all plugin versions up to and including 5.2.11.

An attacker can craft a malicious web page that triggers unauthorized state-changing requests when an authenticated WordPress user visits it. The vulnerability requires user interaction but does not require attacker authentication. Successful exploitation can compromise integrity and availability of the affected WooCommerce payment integration.

Critical Impact
Attackers can trick authenticated WordPress administrators or users into executing unintended actions on the SimplePay plugin, potentially altering payment plugin configuration or triggering unauthorized operations.

Affected Products

codemstory pgall-for-woocommerce (워드프레스 결제 심플페이) WordPress plugin
All versions from n/a through 5.2.11
WordPress sites running WooCommerce with the SimplePay payment integration

Technical Details for CVE-2025-47661

Vulnerability Analysis

The vulnerability stems from missing or improperly implemented CSRF protections in the pgall-for-woocommerce plugin. WordPress plugins are expected to validate requests using nonces via functions such as wp_verify_nonce() or check_admin_referer(). When these controls are absent on state-changing endpoints, an attacker can forge requests that execute in the context of an authenticated victim.

The attack executes over the network and requires the victim to interact with attacker-controlled content, typically by visiting a malicious page while logged into the WordPress site. The scope remains unchanged and confidentiality is not directly affected, but integrity and availability of plugin-managed data can be modified.

Root Cause

The root cause is a missing anti-CSRF token check [CWE-352] on one or more request handlers exposed by the plugin. Without nonce validation or equivalent origin verification, the WordPress backend cannot distinguish between a legitimate user-initiated request and one forged by a third-party site relying on the user's active session cookie.

Attack Vector

An attacker hosts a crafted HTML page containing an auto-submitting form or JavaScript request targeting a vulnerable plugin endpoint on the victim's WordPress site. When a logged-in administrator visits the page, the browser sends the authenticated request, which the plugin processes without verifying its origin. Refer to the Patchstack CSRF Vulnerability Report for the vulnerability disclosure details.

Detection Methods for CVE-2025-47661

Indicators of Compromise

Unexpected changes to pgall-for-woocommerce plugin settings or WooCommerce payment configuration
WordPress access logs showing POST requests to plugin endpoints with external Referer headers
Administrator sessions performing state-changing actions immediately after visiting third-party sites

Detection Strategies

Inspect WordPress request logs for state-changing requests to plugin endpoints missing valid _wpnonce parameters
Correlate administrator browsing activity with subsequent plugin configuration changes
Monitor WooCommerce audit trails for modifications originating outside expected admin workflows

Monitoring Recommendations

Enable WordPress activity logging plugins to capture administrator actions with source IP and referer
Alert on plugin option changes in the wp_options table related to pgall-for-woocommerce
Review web server access logs weekly for suspicious cross-origin POST requests to /wp-admin/ endpoints

How to Mitigate CVE-2025-47661

Immediate Actions Required

Identify all WordPress sites running the pgall-for-woocommerce plugin at version 5.2.11 or earlier
Update the plugin to a patched release once codemstory publishes a version above 5.2.11
Restrict administrator browsing habits and require dedicated browsers or sessions for WordPress administration

Patch Information

At the time of publication, no fixed version above 5.2.11 is referenced in the NVD entry. Site owners should monitor the Patchstack CSRF Vulnerability Report and the plugin vendor's release notes for an official patch.

Workarounds

Deactivate the pgall-for-woocommerce plugin until a patched version is available if the payment integration is not business-critical
Deploy a web application firewall rule to block cross-origin POST requests to plugin admin endpoints lacking a valid _wpnonce parameter
Enforce SameSite=Strict or SameSite=Lax cookie attributes on the WordPress authentication cookies to reduce CSRF exposure
Require administrators to log out of WordPress when not actively managing the site
