Feature Title: Secure PHPUnit Input Handling & Legacy Patching System

Overview This feature addresses a critical security misconfiguration commonly found in vendor/phpunit/phpunit/src/Util/PHP/eval-stdin.php. Historically, this file allowed developers to pipe code into PHPUnit via standard input for testing purposes. However, when exposed on a public-facing web server (due to directory traversal or improper access controls), it allows Remote Code Execution (RCE). Feature Title: Secure PHPUnit Input Handling & Legacy

This feature implements a Security Guard that neutralizes this vulnerability by validating the execution context and disabling insecure input evaluation in web environments. Example of normal CLI usage: echo '<

Example of normal CLI usage:

echo '<?php echo 2+2; ?>' | php vendor/phpunit/phpunit/src/Util/PHP/eval-stdin.php
# Output: 4

8. Why Is This Still a Problem in 2024–2025?

Despite CVE-2017-9841 being 7+ years old, hundreds of sites remain vulnerable because: hundreds of sites remain vulnerable because:

• Developers commit vendor/ to Git and deploy it as-is.
• Shared hosting forces vendor/ inside public_html.
• Outdated tutorials copy PHPUnit into webroot for “quick testing”.
• Automated scans keep finding old Laravel/Symfony projects with abandoned dependencies.

Step 2: Check if it is Web Accessible

Try to access the URL directly using curl (do not send exploit code, just check HTTP status):

curl -k -I https://yoursite.com/vendor/phpunit/phpunit/src/Util/PHP/eval-stdin.php

• 404 Not Found: You are safe (or the file is outside the web root).
• 200 OK or 500: You are vulnerable.
