CVE-2025-30631: AA-Team WordPress Plugins XSS Vulnerability

CVE-2025-30631 Overview

A Reflected Cross-Site Scripting (XSS) vulnerability has been identified in two WordPress plugins developed by AA-Team: WooCommerce Sales Funnel Builder (through version 1.1) and Amazon Affiliates Addon for WPBakery Page Builder (formerly Visual Composer) (through version 1.2). This vulnerability stems from improper neutralization of user-supplied input during web page generation, allowing attackers to inject malicious scripts that execute in the context of a victim's browser session.

Critical Impact

Attackers can exploit this reflected XSS vulnerability to execute arbitrary JavaScript in victims' browsers, potentially stealing session cookies, performing actions on behalf of authenticated users, or redirecting users to malicious websites.

Affected Products

• AA-Team WooCommerce Sales Funnel Builder through version 1.1
• AA-Team Amazon Affiliates Addon for WPBakery Page Builder (formerly Visual Composer) through version 1.2
• WordPress installations utilizing the affected plugin versions

Technical Details for CVE-2025-30631

Vulnerability Analysis

This vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation). The affected WordPress plugins fail to properly sanitize user-controlled input before reflecting it back in HTTP responses. When a user clicks a maliciously crafted link containing JavaScript payload, the script executes within the security context of the vulnerable WordPress site.

The attack requires user interaction—specifically, a victim must click a specially crafted URL. Once triggered, the injected script runs with the same privileges as the victim's session, enabling various malicious activities including credential theft, session hijacking, and unauthorized actions.

Root Cause

The root cause is insufficient input validation and output encoding in the affected plugins. User-supplied data from URL parameters or form inputs is incorporated into the HTML response without proper sanitization or escaping. This allows attackers to break out of the intended HTML context and inject executable JavaScript code.

WordPress plugins that handle user input must implement proper escaping functions such as esc_html(), esc_attr(), and wp_kses() to prevent XSS attacks. The affected versions of these plugins appear to lack adequate implementation of these security controls.

Attack Vector

The attack is network-based and requires user interaction. An attacker crafts a malicious URL containing JavaScript payload parameters and distributes it through phishing emails, social media, or other channels. When a victim clicks the link while authenticated to the WordPress site, the malicious script executes in their browser context.

The reflected nature of this XSS means the payload is not stored on the server but is instead reflected back from the user's request. This makes detection more challenging as there are no persistent artifacts on the compromised system.

Detection Methods for CVE-2025-30631

Indicators of Compromise

• Unusual URL parameters containing JavaScript code or encoded script tags in web server access logs
• Requests to the affected plugin endpoints with suspicious query strings containing <script>, javascript:, or event handlers like onerror, onload
• Reports from users about unexpected behavior or redirects when accessing plugin functionality
• Web Application Firewall (WAF) alerts for XSS attack patterns targeting WordPress endpoints

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block reflected XSS patterns in incoming requests
• Monitor web server access logs for requests containing encoded JavaScript payloads or suspicious URL parameters
• Implement Content Security Policy (CSP) headers to mitigate the impact of successful XSS attacks
• Use WordPress security scanning plugins to identify vulnerable plugin versions

Monitoring Recommendations

• Enable verbose logging on web servers and monitor for anomalous request patterns to plugin endpoints
• Configure alerting for multiple failed XSS attempts from the same source IP address
• Review authentication logs for suspicious session activity following user clicks on external links
• Monitor for unauthorized administrative actions that could indicate session compromise

How to Mitigate CVE-2025-30631

Immediate Actions Required

• Update WooCommerce Sales Funnel Builder to a version newer than 1.1 when available from AA-Team
• Update Amazon Affiliates Addon for WPBakery Page Builder to a version newer than 1.2 when available
• If patches are not available, consider temporarily disabling the affected plugins until a fix is released
• Implement Web Application Firewall rules to filter XSS attack patterns

Patch Information

Administrators should monitor the Patchstack WordPress Vulnerability Database for Amazon Affiliates Addon and Patchstack Advisory for WooCommerce Sales Funnel Builder for updated patch information. Apply security updates from AA-Team as soon as they become available through the WordPress plugin repository.

Workarounds

• Implement strict Content Security Policy (CSP) headers to restrict inline script execution and limit the impact of XSS attacks
• Deploy a Web Application Firewall with XSS detection rules to filter malicious requests before they reach the application
• Restrict access to the affected plugin functionality to authenticated administrators only until patches are available
• Educate users about the risks of clicking suspicious links, particularly those containing unusual URL parameters

# Example Content Security Policy header configuration for Apache
# Add to .htaccess or Apache configuration
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'; img-src 'self' data:; frame-ancestors 'self';"
