Security anti-pattern for missing input validation (CWE-20). Use when generating or reviewing code that processes user input, form data, API parameters, or external data. Detects client-only validation, missing type checks, and absent length limits. Foundation vulnerability enabling most attack classes.

Missing input validation occurs when applications fail to validate data from users or external sources before processing it. This enables SQL Injection, Cross-Site Scripting (XSS), Command Injection, and Path Traversal attacks. Treat all incoming data as untrusted. Validate against strict rules for type, length, format, and range.
Trusting external input without server-side validation. Client-side validation provides no security—attackers bypass it trivially.
