If someone inserts a malicious code or introduces a code into your application, it is called as code injection. The code that is injected can compromise your database integrity and/or compromise privacy properties, security and even data correctness. With code injection one can also steal data and/or give access and authentication control. These injection attacks can affect applications that are user input dependent for execution. You can clean the code injection attack by following various tutorials online.
