Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

PanelSW.Custom.WiX versions before 3.15.0-a46 are affected. WiX Burn-based bundles copy and run binaries from C:\Windows\Temp when run as SYSTEM, and that directory is not fully protected against low-privilege users. A local standard user can hijack those binaries before they load, gaining SYSTEM privileges. Upgrade to 3.15.0-a46 or later.
