CVE-2025-22767: GlobalPayments WooCommerce XSS Vulnerability

CVE-2025-22767 Overview

CVE-2025-22767 is a reflected Cross-Site Scripting (XSS) vulnerability in the Global Payments GlobalPayments WooCommerce plugin for WordPress. The flaw stems from improper neutralization of user-supplied input during web page generation [CWE-79]. All plugin versions up to and including 1.13.2 are affected. An unauthenticated attacker can craft a malicious URL that, when clicked by a victim, executes arbitrary JavaScript in the victim's browser session. The bug carries a CVSS 3.1 score of 7.1 with a scope change, reflecting the ability to impact resources beyond the vulnerable component.

Critical Impact

Successful exploitation enables session hijacking, credential theft, and unauthorized actions performed in the context of authenticated WordPress users, including store administrators.

Affected Products

• Global Payments GlobalPayments WooCommerce plugin versions through 1.13.2
• WordPress sites running WooCommerce with the affected payment integration
• E-commerce deployments using Global Payments for checkout processing

Technical Details for CVE-2025-22767

Vulnerability Analysis

The GlobalPayments WooCommerce plugin reflects user-controlled input back into rendered HTML responses without sufficient encoding or sanitization. When a victim visits a specially crafted URL targeting a vulnerable endpoint, the injected payload executes as JavaScript within the victim's browser. Because the CVSS vector indicates a scope change, the script runs in the context of the WordPress site, granting access to authenticated session data and DOM resources outside the immediate plugin boundary.

The attack requires user interaction. A victim must click a malicious link delivered through phishing, social media, or compromised third-party sites. The unauthenticated nature of the flaw makes it accessible to any remote attacker with knowledge of the vulnerable parameter.

Root Cause

The root cause is missing output encoding when rendering request parameters into HTML responses. Input passed to the plugin is concatenated into the response body without HTML entity encoding or context-aware escaping. This allows attacker-controlled markup, including <script> tags and event handlers, to be parsed and executed by the browser.

Attack Vector

The attack vector is network-based. An attacker constructs a URL pointing to a vulnerable plugin endpoint, embedding a JavaScript payload in a reflected parameter. The payload is delivered to victims through phishing emails, malicious advertisements, or attacker-controlled web pages. When an authenticated WordPress administrator triggers the link, the payload executes with the privileges of that session, enabling actions such as creating new admin accounts, exfiltrating customer payment metadata, or modifying store configuration. See the Patchstack Vulnerability Report for additional technical context.

Detection Methods for CVE-2025-22767

Indicators of Compromise

• Web server access logs containing requests to GlobalPayments plugin endpoints with URL parameters embedding <script>, onerror=, javascript:, or HTML-encoded variants of these tokens
• Unexpected administrative actions originating from authenticated sessions shortly after a user clicked an external link
• New WordPress administrator accounts or modified user roles without corresponding audit trail entries

Detection Strategies

• Inspect HTTP request logs for reflected parameters containing script tags, event handler attributes, or URL-encoded JavaScript payloads targeting /wp-content/plugins/global-payments-woocommerce/ paths
• Deploy Web Application Firewall (WAF) rules that detect XSS payload patterns in query strings and POST bodies
• Correlate referrer headers with administrative state changes to identify sessions hijacked through reflected XSS

Monitoring Recommendations

• Enable verbose access logging on WordPress installations and forward logs to a centralized SIEM for pattern analysis
• Monitor browser-side Content Security Policy (CSP) violation reports for unexpected inline script execution
• Track WooCommerce administrative events including user creation, role changes, and payment configuration modifications

How to Mitigate CVE-2025-22767

Immediate Actions Required

• Update the GlobalPayments WooCommerce plugin to a version newer than 1.13.2 once a patched release is available from the vendor
• Audit WordPress administrator accounts and recent privileged actions for signs of unauthorized changes
• Force password resets and invalidate active sessions for all administrative users on affected stores

Patch Information

The vulnerability affects all versions through 1.13.2. Site operators should consult the Patchstack Vulnerability Report for the latest fixed version guidance and apply the update through the WordPress plugin manager.

Workarounds

• Deploy a WAF with XSS signature detection in front of the WordPress site to filter malicious request parameters
• Implement a strict Content Security Policy that blocks inline scripts and restricts script sources to trusted origins
• Temporarily disable the GlobalPayments WooCommerce plugin until a fixed release is installed if a patch is unavailable
• Train administrative users to avoid clicking unsolicited links referencing the store domain

# Example restrictive CSP header for WordPress (nginx)
add_header Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; base-uri 'self'; frame-ancestors 'self';" always;
