Overview

laravel/framework is a PHP framework for web artisans.

Affected versions of this package are vulnerable to Improper Input Validation via insufficient blocking of the upload of executable PHP content because Illuminate/Validation/Concerns/ValidatesAttributes.php lacks a check for .phar files, which are handled as application/x-httpd-php on systems based on Debian.
