Laravel blade XSS vulnerability

Hello, I've found this article about XSS vulnerability.

blog.nette.org/en/quiz-can-you-defend-against-xss-vulnerability

Could someone explain me please, why Laravel blade doesn't offer this kind of protection out of the box? Or could you please give me some advices of how to prevent this (packages, helper functions etc.)

Because when i really tried this code: @php($str = "foo onclick=evilCode()") <input value={{ $str }}>

It doesn't escape and I need to find solution for this. Possible solution is to use some helper functions inside {{ helper($xxx) }}, but I just wanted to make it automatically. Thank you !
