Vulnerability in Jgraph Drawio-Desktop
CVE-2026-119333
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.
