Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The PanelSwWix4.Sdk NuGet package, prior to 5.0.0-psw-wix.0265-49, is affected. WiX Burn bundles running as SYSTEM use the insecure C:\Windows\Temp directory to copy and load binaries, so a low-privileged local user can replace those binaries and gain SYSTEM privileges. Upgrade to PanelSwWix4.Sdk 5.0.0-psw-wix.0265-49 or later.
