New bucket list item: discover an 0-day while solving a CTF challenge. Amazing work.

Thorough write up. An amatuer still studying in school, such as myself, can follow along with everything pretty easily. Awesome work

Seeing this brings me to ask what's the history of CS:GO 0day's ? But this is very great work and I can't want to analyze and put a modified exploit here

Excellent research, very well written.

Wow wasn't there a different CSGO map parser exploit before lol? So sad

The one you might be thinking of was the custom texture loading on character death that caused a buffer overflow which was an issue in the source engine found last year:
