CVE-2026-119333: draw.io Desktop path traversal privilege escalation on Windows

CVE-2026-119333 · Severity: high · CVSS 7.8 · Published 2026-10-30

draw.io Desktop is a diagram editing application for Windows, macOS, and Linux. On Windows, the application launched system tools using bare executable names, which could be hijacked by attacker-supplied executables placed in the same directory as a diagram file. An attacker could trick a user into opening a malicious diagram archive, allowing arbitrary code execution with the user's privileges.

Vendors: JGraph.

Technical details

The vulnerability exists because src/main/electron.js launched powershell and attrib without absolute paths. When a user opened a .drawio file from File Explorer, the diagram's directory became the current working directory, allowing a colocated attrib.exe or powershell.bat to be resolved and executed before the legitimate system executable. Exploitation requires the victim to extract an attacker-supplied archive and open a diagram file with Local Fonts enabled or when draft/backup attributes are updated.
