What is injections?

Injections are a class of security vulnerabilities that occur when untrusted data is sent to an interpreter as part of a command or query. This allows an attacker to inject malicious code or commands into the application, potentially leading to data breaches, system compromise, or denial of service. Common examples include SQL injection, command injection, and cross-site scripting (XSS). Injections are often caused by a lack of proper input validation and sanitization.
