CVE-2026-45322 Details
Description
Microsoft UFO open-source framework for intelligent automation across devices and platforms. Microsoft UFO tagged releases up to and including v3.0.0 contain an OS command injection vulnerability in the shell action replay path. In affected releases, ShellReceiver.run_shell() passes a command string from action parameters directly to subprocess.Popen() with shell=True and executable=powershell.exe. The same shell-execution behavior is also reachable through ShellReceiver.execute_command(). The shell receiver is invoked by action classes such as RunShellCommand.execute() and ExecuteCommand.execute(), which forward stored action parameters to the shell receiver. Because UFO stores planned and executed actions in per-session JSON records, an attacker who can write or modify a session/action JSON file can plant a shell action. When the session is resumed or replayed, UFO executes the attacker's command as the UFO process user.
A command injection vulnerability has been identified in the Microsoft UFO open-source framework, specifically in tagged releases up to and including v3.0.0. The issue arises in the shell action replay path, where the ShellReceiver.run_shell() method passes command strings from action parameters directly to subprocess.Popen() with shell=True and executable=powershell.exe. This behavior is also accessible through ShellReceiver.execute_command(). The vulnerability allows an attacker to execute arbitrary PowerShell commands by manipulating session/action JSON files, which UFO processes as trusted input during action replay.
Users are advised to update to the latest version of Microsoft UFO, as the main branch contains a fix for this vulnerability. However, no tagged security release has been made available yet.
