For example, an attacker can send a crafted request to the vulnerable system:
The directory /vendor/phpunit/phpunit/src/Util/PHP/ must be exposed and accessible from the public internet. vendor phpunit phpunit src util php eval-stdin.php cve
This line reads the raw body of an HTTP request (via php://input ) and executes it using the eval() function. If the /vendor folder is publicly accessible from the web, anyone can send a crafted POST request to execute arbitrary code on your server.

The string vendor/phpunit/phpunit/src/Util/PHP/eval-stdin.php represents one of the most heavily targeted files in web security history. Cataloged as , this critical remote code execution (RCE) vulnerability continues to dominate global malicious threat scanning logs. Despite its age, a lethal combination of unauthenticated access, trivial exploitation, and systemic deployment flaws keeps this flaw highly relevant for modern security teams. Anatomy of the Vulnerability If the /vendor folder is publicly accessible from
When deploying modern PHP projects via Composer, dependencies are stored in a root-level directory called /vendor . If a web server's document root is misconfigured to point to the project root instead of a public directory (like /public or /www ), the entire /vendor tree becomes world-readable.
