MECCHA CHAMELEON can't hide from the RCE
TL;DR: We found another delayed RCE in MECCHA CHAMELEON. When playing on an attacker’s map, they can abuse an exposed function to arbitrarily write files to the victim’s system. This can lead to remote code execution on the victim’s system after a restart. We reported the issue to the game’s maintainers, and they fixed the vulnerability in the 4.0.0 update. This update is automatically installed before launching the game.
