FunnelKit WordPress Plugin SQL Injection via Cart Parameter

The FunnelKit Automations – Email Marketing Automation and CRM for WordPress & WooCommerce plugin for WordPress is vulnerable to time-based SQL Injection via the 'bwfan_cart_id' parameter in all versions up to, and including, 3.8.5.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Exploitation is a two-step persisted attack: an unauthenticated attacker submits a crafted bwfan_cart_id value during a guest Store API checkout (requiring only a publicly obtainable WooCommerce cart nonce), and the injection fires when a scheduled Action Scheduler job later reloads the stored meta upon order status transition out of pending, failed, or cancelled.

Casky was already ahead

This CVE exploits attack patterns that Casky's 323matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

The FunnelKit Automations plugin for WordPress contains a time-based SQL injection vulnerability in the 'bwfan_cart_id' parameter that allows unauthenticated attackers to execute arbitrary SQL queries. This vulnerability affects all versions up to 3.8.5.2 and stems from insufficient escaping and lack of prepared statement usage in database queries. With a CVSS score of 7.5, this poses a significant risk to any WordPress or WooCommerce installation using this popular email marketing and CRM plugin. Attackers can exploit this flaw to extract sensitive data, including customer information, credentials, and transaction details, without requiring authentication.

Casky.ai's 754 security skills, powered by Claude AI with extended reasoning capabilities, map this vulnerability to MITRE ATT&CK techniques TA0001 (Initial Access) and TA0043 (Reconnaissance). The platform's 323 matching skills enable detection of reconnaissance activities where attackers probe the 'bwfan_cart_id' parameter with time-delay payloads to confirm SQL injection susceptibility, followed by data exfiltration attempts. Practitioners using Casky would observe findings highlighting suspicious parameter manipulation patterns, unusual database query timing anomalies, and CWE-89 (SQL Injection) signatures in web application logs. Extended reasoning capabilities allow the platform to correlate these indicators with known exploitation patterns, helping security teams identify both active exploitation attempts and historical compromise indicators before malicious actors achieve data extraction.
