CVE-2025-24551 Overview
A Reflected Cross-Site Scripting (XSS) vulnerability has been identified in the Radio Buttons and Swatches for WooCommerce WordPress plugin developed by oneteamsoftware. This vulnerability allows attackers to inject malicious scripts through improperly neutralized user input during web page generation, potentially compromising user sessions and sensitive data on affected WooCommerce stores.
Critical Impact
Attackers can execute arbitrary JavaScript code in the context of victim browsers, potentially leading to session hijacking, credential theft, and malicious actions performed on behalf of authenticated users.
Affected Products
- Radio Buttons and Swatches for WooCommerce plugin versions up to and including 1.1.20
- WordPress installations running the vulnerable plugin
- WooCommerce stores utilizing variation display functionality

Technical Details for CVE-2025-24551
Vulnerability Analysis
This vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation). The flaw exists in how the Radio Buttons and Swatches for WooCommerce plugin processes user-supplied input before rendering it in web pages. When input is not properly sanitized or encoded, attackers can craft malicious URLs containing JavaScript payloads that execute when victims click on them.
Reflected XSS attacks typically require social engineering to convince victims to visit a specially crafted URL. Once the victim accesses the malicious link, the injected script executes within their browser session with full access to the page context, cookies, and session tokens associated with the vulnerable WordPress site.
Root Cause
The root cause of this vulnerability lies in insufficient input validation and output encoding within the plugin's codebase. User-controlled data is reflected back to the browser without proper sanitization, allowing HTML and JavaScript injection. The plugin fails to implement adequate security controls such as escaping special characters or using Content Security Policy headers to prevent script execution.
Attack Vector
The attack requires a victim to click on a malicious link containing the XSS payload. The attacker constructs a URL targeting the vulnerable endpoint in the Radio Buttons and Swatches for WooCommerce plugin, embedding JavaScript code within a parameter value. When the victim's browser processes the response, the malicious script executes in the context of the WooCommerce store's domain.
The exploitation mechanism involves crafting a malicious URL that includes JavaScript code in a vulnerable parameter. When the page is rendered, the unsanitized input is included directly in the HTML response, causing the browser to execute the attacker's script. This can lead to cookie theft, keylogging, phishing overlays, or other malicious actions performed within the victim's authenticated session.
Detection Methods for CVE-2025-24551
Indicators of Compromise
- Unusual URL patterns in web server logs containing encoded JavaScript or HTML tags directed at WooCommerce-related endpoints
- User reports of unexpected behavior, pop-ups, or redirects when accessing product variation pages
- Session tokens or authentication cookies being transmitted to external domains
- Suspicious referrer URLs in access logs indicating XSS payload delivery attempts
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect and block common XSS payloads in URL parameters
- Monitor web server access logs for requests containing suspicious characters such as <script>, javascript:, or encoded variants like %3Cscript%3E
- Deploy browser-based security monitoring to detect anomalous script execution on WooCommerce pages
- Utilize WordPress security plugins with XSS detection capabilities to scan for malicious request patterns
Monitoring Recommendations
- Enable verbose logging for the WordPress environment and review logs for injection attempts
- Configure alerting for requests containing common XSS signatures targeting plugin endpoints
- Monitor Content Security Policy violation reports to identify attempted script injections
- Track user-reported security incidents related to unexpected browser behavior on product pages
How to Mitigate CVE-2025-24551
Immediate Actions Required
- Update the Radio Buttons and Swatches for WooCommerce plugin to a version newer than 1.1.20 as soon as a patched release is available
- Implement a Web Application Firewall with XSS filtering rules to block malicious requests
- Review and audit web server logs for any signs of exploitation attempts
- Consider temporarily disabling the plugin if business requirements permit until a patch is released
Patch Information
Organizations should monitor the official WordPress plugin repository and the vendor's website for security updates addressing this vulnerability. The Patchstack XSS Vulnerability Report provides additional details about this vulnerability and remediation guidance.
Workarounds
- Deploy WAF rules to filter requests containing XSS payloads targeting the vulnerable plugin parameters
- Implement Content Security Policy headers to restrict script execution sources and mitigate XSS impact
- Use input validation plugins or custom filters to sanitize user input before processing
- Educate users about the risks of clicking on suspicious links, particularly those containing unusual URL parameters
# Example: Apache .htaccess WAF-style rule to block common XSS patterns
RewriteEngine On
RewriteCond %{QUERY_STRING} (<script|%3Cscript|javascript:|%6A%61%76%61%73%63%72%69%70%74) [NC]
RewriteRule .* - [F,L]
