Laravel 8.x image upload bypass — Zero Day

In this write-up we’re gonna walk through bypassing laravel image upload , which is one the most popular web application framework written in php.

By bypassing laravel’s image validation we can achieve other attacks, first and most loved is XSS and as it is an stored xss we can write a full exploit that let us bypass CSRF and then we are free to do whatever we want with higher privilege and I give it to you in this write-up , I also researched for remediation on this attack and I give that one too.
