What is CVE-2025-54081?

The Sunshine game stream host, developed by LizardByte, has a vulnerability due to an unquoted executable path in the Windows service SunshineService. This issue arises when Sunshine is installed in a directory containing spaces. The Service Control Manager (SCM) may interpret the executable path incrementally, potentially allowing the execution of a malicious binary if placed earlier in the search path. Users are advised to upgrade to version 2025.923.33222 or later to mitigate this risk.
