The directory structure you are seeing is characteristic of a Remote Code Execution (RCE) vulnerability known as CVE-2017-9841.
This specific path—vendor/phpunit/phpunit/src/Util/PHP/eval-stdin.php—is a known security risk when exposed to the public internet. Why It Is Dangerous
The file eval-stdin.php was designed to receive PHP code via a standard input stream for testing purposes. In older versions of PHPUnit, this file incorrectly used php://input to read data, which allows an attacker to send an HTTP POST request containing malicious code that the server will then execute automatically.
