Open redirect detected.

• Rule ID: php_lang_open_redirect
• Languages: php
• Source: open_redirect.yml

Description

A redirect using unsanitized user input is bad practice and puts your application at greater risk of phishing attacks.

Remediations

❌ Do not use unsanitized user input when constructing URLs

✅ Instead, ensure the input is validated by using a safe list or a mapping when constructing URLs

  $paths = [
    "1" => "/planes",
    "2" => "/trains",
    "3" => "/automobiles",
  ];

  $transport = $_GET["transport"];
  header("Location: {$paths[$transport]}", true, 301);
