Activision released an update this week that addressed all known vulnerabilities in Call of Duty: Modern Warfare 2 from 2009 on Steam. The studio stated that the patch covers remote code execution exploits that had persisted on the platform. It added that the team continues supporting legacy titles and plans additional updates soon. Earlier reports described the Steam version as a frequent target for hacks. Jez Corden noted the fix and separately asked about similar issues affecting classic Call of Duty games through Xbox backward compatibility.
