For example, an attacker can send a crafted request to the vulnerable system:
A proof-of-concept exploit has been publicly disclosed, demonstrating how an attacker can execute arbitrary code on a vulnerable system. The exploit involves providing malicious input to the eval-stdin.php script, which is then executed by the vulnerable PHPUnit instance.
The vulnerability arises from the fact that the eval-stdin.php script does not properly sanitize user input. An attacker can exploit this by providing malicious input, which will be executed on the server without proper validation. This allows for arbitrary code execution, making the vulnerability particularly severe. vendor phpunit phpunit src util php eval-stdin.php cve
composer update phpunit/phpunit Alternatively, download the patched version of PHPUnit from the official GitHub repository:

The PHPUnit vendor has released a patch for the vulnerability, which is included in PHPUnit version 9.5.0. The vendor has also provided guidance on mitigating the vulnerability.
