Protect Your FunnelKit Funnel Builder from SQL Injection Attacks

SourceCVE-2023-50856

The FunnelKit Funnel Builder plugin for WordPress is affected by a SQL injection vulnerability. SQL injection is a type of attack where malicious code is inserted into SQL queries, which are used to retrieve data from a database. This allows attackers to view, modify or delete data in the database.

In this case, the plugin may not properly sanitize user-supplied input before using it in SQL queries. By inputting specially crafted SQL code, an attacker could exploit this to view sensitive data like admin credentials or payment information. They could also manipulate or delete database records.

SQL injection attacks work by appending SQL code onto the end of queries. For example, a login form may send a username and password to a backend database query like “SELECT * FROM users WHERE username=’$username’ AND password=’$password’”. An attacker could enter “test’; DROP TABLE users;–” for the username, which would cause the query to delete the entire users table if not sanitized properly.

To protect yourself, users should update their FunnelKit Funnel Builder installation to the latest version, which has addressed this vulnerability. Website owners should also ensure their database credentials have strong unique passwords. Being vigilant about applying security updates is key to avoiding many common exploits.
