A few days ago, Unity disclosed a remote code execution (RCE) vulnerability which was impacting versions dating back to 2017. This effectively meant that almost all games and apps that use Unity 2017.1 are vulnerable to attacks from malicious actors. Although Unity has already released patches in the latest version of its software, Microsoft has recently published a separate advisory since many of its apps and services are affected too.

The issue in question is being publicly tracked as CVE-2025-59489 and it has been assigned a CVSS severity score of 8.4/10, which is pretty high. Microsoft says that it is currently evaluating how many apps and games developed and published by the firm are impacted by the vulnerability, and is in the process of rolling out updates for all of them.

Microsoft has emphasized that Unity software downloaded on Windows, Android, Linux, and macOS is affected. However, customers using consoles, cloud gaming, and iOS should consider themselves safe. Importantly, Microsoft Mesh is impacted too, since it uses Unity as well. Customers utilizing Mesh should update to the latest version of the software, and while this shouldn't affect previously scheduled events, Redmond has suggested updating Mesh apps before joining a meeting just to avoid any undue disruption.

The following Microsoft apps and games have been confirmed as impacted by the Unity vulnerability, and updates are being rolled out for them:
