Background
CodeIgniter is an open-source PHP web application framework that provides a simple and elegant toolkit for creating full-featured web applications. It is widely used for its lightweight nature, speed, and ease of use. However, versions up to 3.1.13 of CodeIgniter are vulnerable to SQL Injection attacks through the where_in() function in the system\database\DB_query_builder.php file.
Vulnerability Detail
The SQL Injection vulnerability in CodeIgniter allows an attacker to manipulate SQL queries by injecting malicious input. This can lead to unauthorized access, data leakage, data manipulation, and potentially complete compromise of the application and underlying database. The vulnerability arises due to insufficient input validation and sanitization in the where_in() function, which allows an attacker to craft specially crafted input to execute arbitrary SQL statements.
How To Fix
Minimum fixed version
3.1.13
This is the first release that contains the fix.

Workaround
As a temporary workaround, developers can manually sanitize and validate user input before using it in SQL queries. This can be done by using appropriate functions or libraries to escape special characters and ensure that only valid input is used in queries. However, this approach is error-prone and may not provide complete protection against all possible attack vectors. Therefore, upgrading to the latest version of CodeIgniter is strongly recommended.
Conclusion
The SQL Injection vulnerability in CodeIgniter can have serious consequences for the security and integrity of web applications. It is crucial to promptly upgrade to the latest version of CodeIgniter and follow secure coding practices to mitigate the risk of SQL Injection attacks.
