CVE-2025-30906 Overview
CVE-2025-30906 is a reflected cross-site scripting (XSS) vulnerability in the Plugin Oficial – Getnet para WooCommerce WordPress plugin developed by lisandragetnet. The flaw affects all plugin versions up to and including 1.7.3. It stems from improper neutralization of user-supplied input during web page generation, classified under [CWE-79]. Attackers can craft malicious URLs that, when clicked by a victim, execute arbitrary JavaScript in the victim's browser session within the WordPress site context. The vulnerability requires user interaction and can lead to session token theft, credential harvesting, or unauthorized actions performed on behalf of authenticated users.
Critical Impact
Successful exploitation allows attackers to execute arbitrary JavaScript in victim browsers, enabling session hijacking, credential theft, and unauthorized administrative actions on affected WooCommerce stores.
Affected Products
- Plugin Oficial – Getnet para WooCommerce (wc-checkout-getnet) versions n/a through 1.7.3
- WordPress installations running the vulnerable plugin
- WooCommerce-based e-commerce sites using Getnet payment integration

Technical Details for CVE-2025-30906
Vulnerability Analysis
The vulnerability resides in the wc-checkout-getnet plugin, which integrates Getnet payment processing with WooCommerce. The plugin fails to sanitize or encode user-controlled input before reflecting it back in HTTP responses. An attacker crafts a URL containing malicious JavaScript payloads in query parameters or form fields processed by the plugin. When a victim visits the crafted URL, the unsanitized input is rendered directly into the HTML output, causing the browser to execute the embedded script.
Reflected XSS attacks typically rely on phishing or social engineering to deliver the malicious link. Because the script executes in the victim's browser under the site's origin, it can access session cookies, perform actions on behalf of the user, and read sensitive page content. Administrators visiting the malicious link are particularly at risk, as their privileged sessions enable broader compromise.
Root Cause
The root cause is missing output encoding and input validation in the plugin's request handling code. User-supplied parameters are concatenated into HTML responses without escaping characters such as <, >, and ". This allows attacker-controlled content to break out of intended HTML contexts and inject executable script tags or event handlers.
Attack Vector
Exploitation occurs over the network and requires user interaction. The scope is changed, meaning the impact extends beyond the vulnerable component to affect the user's browser session. The attacker hosts or distributes a crafted URL targeting the affected plugin endpoint. When the victim clicks the link, the reflected payload executes in their browser. Refer to the Patchstack Vulnerability Report for technical details.
Detection Methods for CVE-2025-30906
Indicators of Compromise
- HTTP requests to wc-checkout-getnet plugin endpoints containing encoded script tags, event handlers, or JavaScript URI schemes in query parameters
- Web server access logs showing suspicious URL parameters with patterns such as <script>, onerror=, onload=, or javascript:
- Unusual outbound requests from administrator browser sessions to attacker-controlled domains following clicks on inbound links
Detection Strategies
- Inspect WordPress access logs for requests to plugin URLs containing URL-encoded XSS payloads or unusual character sequences
- Deploy a web application firewall with rules tuned to identify reflected XSS patterns targeting WooCommerce checkout endpoints
- Correlate referrer headers with phishing campaigns or suspicious external domains delivering crafted links
Monitoring Recommendations
- Enable verbose logging on the WordPress site and forward logs to a centralized analysis platform for query parameter inspection
- Monitor administrator account activity for anomalous session behavior, including unexpected configuration changes or new user creation
- Track plugin version inventory across all WordPress installations to identify systems still running wc-checkout-getnet1.7.3 or earlier
How to Mitigate CVE-2025-30906
Immediate Actions Required
- Audit all WordPress installations for the presence of the Plugin Oficial – Getnet para WooCommerce plugin and identify versions 1.7.3 or earlier
- Deactivate the vulnerable plugin until a patched version is installed if active exploitation is suspected
- Apply a web application firewall ruleset that filters reflected XSS payloads targeting the plugin endpoints
Patch Information
At the time of NVD publication, no fixed version is listed in the advisory. Administrators should monitor the Patchstack Vulnerability Report and the official plugin repository for an updated release that addresses the input neutralization flaw.
Workarounds
- Disable the wc-checkout-getnet plugin until vendor remediation is available, and route checkout traffic through an alternative payment integration
- Implement Content Security Policy (CSP) headers on the WordPress site to restrict inline script execution and reduce XSS impact
- Train administrators and staff to avoid clicking unsolicited links pointing to the WordPress store domain, particularly those with unusual query parameters
# Example CSP header to mitigate reflected XSS impact
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; base-uri 'self'; frame-ancestors 'self';"
