Hi Guys,

My Name is Murtada Kamil, I am a bug hunter from Iraq

This is my first write up, and I would like to share with you my bug that I found in picturepush through their bug bounty program

During my recent bug bounty hunt, I came across a critical and yet simple vulnerability.this bug made me able to read any victim album password
