Machine-written summary

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

The WiX Toolset packages wix (versions below 3.14.1, and 4.0.0 up to but not including 4.0.5) and WixToolset.Util.wixext (versions below 4.0.5) are affected. A standard user who can write to a per-user folder that a per-machine installer is told to remove with RemoveFolderEx can create a directory junction there pointing to a protected directory. When an administrator runs the installer, the protected target can be deleted. Upgrade wix to 3.14.1 or 4.0.5, and WixToolset.Util.wixext to 4.0.5.
