CS:GO and other source games have had loads of serious vulnerabilities. I've found a few myself just by looking at the leaked source code: https://github.com/perilouswithadollarsign/cstrike15_src https://github.com/perilouswithadollarsign/cstrike15_src The engine code is very old, and CS:GO itself was not developed by valve but by Hidden Path Entertainment initially as a port of CS: Source to consoles and they didn't really do a great job.
