Features
We just published the November 2025 release of the Magic Leap OS. This release patches a security vulnerability that Unity identified in October that may impact applications built with the Unity Engine after 2017.1.
Multiple system applications in the Magic Leap OS were built with Unity and patched in this release. There is no evidence of any exploitation of the vulnerability, nor has there been any impact on users or customers.
Additionally, Magic Leap has patched our first-party applications that were built with Unity. We recommend updating these applications. Patched downloads are available here.
