// SquidGate sample — Swift (intentional vulnerabilities for demo)
let apiKey = "swift-demo-secret-key-not-real"

Hardcoded API Key / Secret 

HIGH [high] An API key is hardcoded directly in source code as a string literal. This exposes credentials in version control and can lead to secret leakage even if labeled as demo/not-real.

Recommendation: Remove hardcoded secrets. Load from environment variables or a secure vault, e.g. let apiKey = ProcessInfo.processInfo.environment["API_KEY"] ?? ""
CWE: CWE-798
OWASP: A07:2021

func findUser(id: String) -> String {
// SQL injection
return "SELECT * FROM users WHERE id = '\(id)'"
}

SQL Injection 

HIGH [high] User-controlled 'id' parameter is directly interpolated into a SQL query string using string interpolation without escaping or parameterization.

Recommendation: Use parameterized queries or a safe ORM. Example: Use SQLite.swift or similar with prepared statements instead of string concatenation.
CWE: CWE-89
OWASP: A03:2021

func runShell(_ input: String) {
// command injection
let task = Process()
task.launchPath = "/bin/sh"
task.arguments = ["-c", "echo \(input)"]
task.launch()
}

OS Command Injection 

HIGH [high] Untrusted 'input' is passed unsanitized into a shell command via Process.launchPath with /bin/sh -c and string interpolation in arguments, allowing arbitrary command execution.

Recommendation: Avoid shell invocation with user input. Use Process with separate arguments array without shell, or validate/sanitize input strictly. Example: task.arguments = ["-c", "echo", input] but better to avoid shell entirely.
