An injection attack is where an untrusted input is introduced into a program. As it gets processed as part of a query or command, it interferes with its execution. Developers have come up with the OWASP Top 10, which is a standardized awareness document developed upon broad consensus on critical security risks. Injection attacks are still serious because vulnerabilities are exploited in varied ways. Nonetheless, it is important to always update and patch, use firewalls, and use appropriate privileges.
