CVE-2025-24632: WooCommerce Dynamic Pricing XSS Flaw

CVE-2025-24632 Overview

A Reflected Cross-Site Scripting (XSS) vulnerability has been identified in the Advanced Dynamic Pricing for WooCommerce plugin developed by algol.plus. This vulnerability allows attackers to inject malicious scripts into web pages by exploiting improper neutralization of user-supplied input during web page generation. The flaw exists in versions up to and including 4.9.0 of the plugin.

Critical Impact

Attackers can execute arbitrary JavaScript code in the context of a victim's browser session, potentially leading to session hijacking, credential theft, and malicious actions performed on behalf of authenticated users.

Affected Products

• Advanced Dynamic Pricing for WooCommerce plugin versions through 4.9.0
• WordPress installations running the vulnerable plugin versions
• WooCommerce stores utilizing the Advanced Dynamic Pricing functionality

Technical Details for CVE-2025-24632

Vulnerability Analysis

This vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation), commonly known as Cross-Site Scripting (XSS). The Reflected XSS variant occurs when user-supplied data is immediately returned by a web application in an error message, search result, or any other response that includes input provided by the user without proper encoding or validation.

In the context of the Advanced Dynamic Pricing for WooCommerce plugin, user input is not properly sanitized before being rendered in the browser, allowing an attacker to craft malicious URLs containing JavaScript payloads. When a victim clicks on such a link, the malicious script executes within their browser session with full access to the page context.

Root Cause

The root cause of this vulnerability stems from insufficient input validation and output encoding within the plugin. User-controlled parameters are reflected in HTTP responses without proper sanitization, allowing HTML and JavaScript injection. WordPress plugins that handle pricing calculations and display dynamic content are particularly susceptible to XSS if they fail to implement proper escaping functions such as esc_html(), esc_attr(), or wp_kses().

Attack Vector

The attack requires social engineering to convince a victim to click on a malicious link containing the XSS payload. The attacker crafts a specially designed URL targeting the vulnerable plugin endpoint with embedded JavaScript code. When the victim visits this URL while authenticated to the WordPress site, the malicious script executes in their browser context.

Successful exploitation enables attackers to steal session cookies, capture keystrokes, redirect users to phishing sites, modify page content, or perform actions as the authenticated user. For WooCommerce administrators, this could lead to complete site compromise, including access to customer payment information and order data.

Detection Methods for CVE-2025-24632

Indicators of Compromise

• Unusual URL parameters containing JavaScript code or HTML tags in web server access logs
• User reports of unexpected redirects or pop-ups when accessing WooCommerce pricing pages
• Browser console errors indicating blocked inline scripts or Content Security Policy violations
• Suspicious referrer URLs in analytics pointing to external domains

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect common XSS payload patterns in request parameters
• Monitor server logs for URL-encoded JavaScript keywords such as %3Cscript%3E, javascript:, or onerror=
• Deploy browser-side Content Security Policy headers to mitigate script execution from untrusted sources
• Use security scanning tools to identify reflected input in HTTP responses

Monitoring Recommendations

• Enable detailed logging for the Advanced Dynamic Pricing for WooCommerce plugin endpoints
• Configure SIEM alerts for patterns matching XSS attack signatures in web traffic
• Regularly audit user session activity for anomalous behavior following external referrals
• Monitor for unexpected changes to WooCommerce configuration or user accounts

How to Mitigate CVE-2025-24632

Immediate Actions Required

• Update the Advanced Dynamic Pricing for WooCommerce plugin to a patched version newer than 4.9.0
• Review web server logs for any evidence of exploitation attempts
• Implement Content Security Policy headers to restrict inline script execution
• Consider temporarily disabling the plugin until a patch is applied if immediate update is not possible

Patch Information

A security update addressing this Reflected XSS vulnerability should be obtained from the plugin vendor. Site administrators should check the WordPress plugin repository or the Patchstack Vulnerability Report for the latest security updates and patching guidance.

Workarounds

• Deploy a Web Application Firewall with XSS filtering rules to block malicious payloads
• Implement strict Content Security Policy headers restricting script sources to trusted origins
• Limit plugin functionality to authenticated administrators only until patched
• Use WordPress security plugins that provide input sanitization and output encoding enforcement

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