# draw.io Desktop on Windows: planted executable runs when opening a diagram

draw.io Desktop for Windows launches powershell and attrib by bare name, so a file placed next to a diagram can be run instead of the system tool. An attacker who gets a victim to extract an archive and open a .drawio file can run code as that user.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed draw.io Desktop version in Help > About, or the app's package metadata; versions below `31.5.2` are affected.
- Confirm the app runs on Windows; the description covers only the Windows build.

## Fix

- draw.io Desktop: move to `31.5.2` or later.

## From the sources

draw.io Desktop is the official Electron build of draw.io. Prior to 31.5.2, the Windows application launched powershell and attrib by bare executable name from src/main/electron.js. When draw.io Desktop was not already running, opening a diagram from File Explorer made the diagram directory the current working directory, allowing a colocated attacker-controlled powershell.bat or attrib.exe to be resolved before the intended system executable. A victim who extracted an attacker-supplied archive and cold-opened its legitimate .drawio file could therefore execute attacker-controlled code when Local Fonts were enabled or when draft or backup attributes were updated. This issue is fixed in version 31.5.2.
