Lifecycle Timeline

The Whole Enquiry Cart for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘woowhole_success_msg’ parameter in all versions up to, and including, 1.2.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
AnalysisAI
Stored Cross-Site Scripting (XSS) in Whole Enquiry Cart for WooCommerce plugin allows authenticated administrators to inject arbitrary JavaScript via the 'woowhole_success_msg' parameter, affecting all versions up to 1.2.1. The injected scripts execute for all users viewing affected pages, but exploitation is restricted to multi-site WordPress installations or sites with unfiltered_html disabled, and requires administrator-level privileges. No public exploit code or active exploitation has been identified at time of analysis.
Technical ContextAI
This vulnerability exploits insufficient input sanitization and output escaping in the WordPress plugin's handling of the 'woowhole_success_msg' parameter. The root cause is a CWE-79 (Improper Neutralization of Input During Web Page Generation) class flaw where user-controlled input from administrators is rendered directly into page output without proper HTML entity encoding or sanitization. The vulnerability manifests as Stored XSS rather than Reflected XSS because the malicious payload is persisted (likely in WordPress options or post metadata) and executed whenever the page is accessed. WordPress's unfiltered_html capability normally allows administrators to use raw HTML; however, on multi-site installations or when this capability is explicitly disabled, the plugin fails to provide adequate secondary controls to prevent XSS injection through this administrative interface parameter.
RemediationAI
Update the Whole Enquiry Cart for WooCommerce plugin to a patched version released after 1.2.1; specific patch version information is not provided in available data, so administrators should check the plugin repository (https://plugins.trac.wordpress.org/browser/whole-cart-enquiry/trunk/admin.php#L53) or contact idealwebdesignslk directly for the latest security release. As an interim mitigation for multi-site installations or environments with unfiltered_html disabled, restrict the woowhole_success_msg parameter from administrator input or implement additional server-side output escaping by adding wp_kses_post() or esc_html() calls around the parameter rendering. Monitor the WordPress plugin repository for security updates and enable automatic plugin updates where possible.
