Activision has recently released new and critical security updates for "Call of Duty: WWII" and "Call of Duty: Black Ops III" on Steam. These updates are designed to address the recently discovered vulnerabilities that could affect player safety, multiplayer stability, and overall online security. The patches aim to protect gamers from exploits and hacking risks while keeping servers secure and playable. Players are now urged to update immediately before joining public lobbies. These updates have strengthen defenses against Remote Code Execution (RCE) attacks and other exploit threats that have circulated online for months.
Call of Duty: WWII:-
In World War II multiplayer, vulnerabilities stem from older network code and matchmaking design that could let malicious users execute harmful commands on another player's system. So, it received silent updates recently on February 12, 2026 and received a sudden security update on February 28, 2026. This implements updates that have reportedly disabled several popular third-party modification tools, such as "Zombie Trainers" and "Loadout Editors", which now cause the game to crash on launch.
Call of Duty: Black Ops III:-
In this game, exploits have persisted because its original anti-cheat systems are outdated, and decades-old networking code was never patched for modern cybersecurity threats. Hence, latest updates, which released around February 19, 2026 that tweak internal binaries and multiplayer systems to reduce these attack vectors and improve the session handling.
Reasons Behind the Security Updates:
Speaking of exact reasons, many players reported that Call of Duty: WWII was being targeted by an RCE exploit, allowing hackers to run arbitrary code on someone else’s PC during multiplayer matches. To explain and prove this matter, users described everything from crashes to remote command prompts that were appeared mid-game, and highlighting just how dangerous the flaw was.
When Call of Duty: WWII launched on Xbox and PC Game Pass in mid-2025, its player counts spiked, which opened the door for exploit activity and made vulnerabilities more visible and exploitable online. On the other hand, Black Ops III never received sustained security support after its launch, leaving old network code and anti-cheat systems vulnerable.
Serious RCE hacks and remote threats were reported by players on Call of Duty: WWII soon after its Game Pass launch in July 2025. This was the first time that these exploits were noticed. These security updates were released specifically on Steam (PC). Activision did not publicly list updates on consoles.
The updates likely enforce stronger network session checks, better anti-cheat loops, and binary hardening to prevent easy exploitation. Community posts show that some players claim that the vulnerabilities will remain because the old codebase is hard to fully secure. This suggests that multiple patch waves may be needed to solve these issues. Even after updating the game, players must join public lobbies carefully and keep OS and antivirus updated.
