This video discusses a security vulnerability in the PC version of Call of Duty: World War II available on Game Pass. The vulnerability, a Remote Code Execution (RCE), allowed hackers to execute commands on players' computers, leading to actions like opening command prompts, changing desktop backgrounds, and even remote shutdowns. The video explains what an RCE is, why older games ported to PC with minimal updates are more susceptible, and the potential for these vulnerabilities to be sold on the dark web for more malicious purposes. The PC version of the game was temporarily taken offline due to this issue.
