Activision has removed Call of Duty: WWII from the Microsoft Store and PC Game Pass due to reports of player hacks linked to a critical security vulnerability that allowed hackers to gain remote access to players' computers. This issue arose shortly after the game's introduction to Microsoft’s Game Pass in late June 2025, with players experiencing computer freezes, unexpected command prompts, shutdowns, and direct messages from hackers. The vulnerability, known as Remote Code Execution (RCE), was present in the outdated version on the Microsoft Store, while the Steam version had been patched. Activision has not provided details on the removal or a timeline for the game's return, and players are advised against downloading it from any platform until security concerns are addressed.
