Laravel is a web application framework. Prior to versions 12.60.0 and 13.10.0, a CRLF injection vulnerability in Laravel's email validation, in combination with how Symfony Mailer and Symfony Mime handle certain character sequences, may allow an unauthenticated attacker to interfere with outbound email processing in applications that send mail to user-supplied addresses. This issue has been patched in versions 12.60.0 and 13.10.0.
