First of all, this is the first browser-related CTF challenge I ever made. I’m very glad to see that players are actively participating. In the end, 29 teams solved Chromium RCE, 7 teams solved Chromium SBX and 2 teams solved Chromium Fullchain, huge props to all those teams.
There are already several public write-ups and I have learned a lot from them. Nevertheless, I would like to provide a summary from my perspective and provide more details.
