NewCVE-2026-22864 (opens in a new tab)How to fix?
Upgrade deno_subprocess_windows to version 0.15.0 or higher.
Overview
deno_subprocess_windows is a Subprocess API implementation for Windows.
Affected versions of this package are vulnerable to Arbitrary Command Injection when executing batch files on Windows. An attacker can execute arbitrary commands by supplying specially crafted input that is processed by the Windows CreateProcess function, e.g., through node:child_process or Deno.Command.spawn().
Note:
This is caused by an incomplete fix for CVE-2025-61787.
PoC
const command = new Deno.Command('./test.BAT', {
args: ['&calc.exe'],
});
const child = command.spawn();
