## Overview

Codex Desktop for Windows does not correctly check quotation marks in project paths from Windows Explorer. If a user selects "Open project in ChatGPT" for an attacker-controlled library's child item, the path can add application startup arguments. These arguments can run attacker-controlled code with the current Windows user's permissions before sign-in or project trust approval.

## Affected

- `codex_desktop_for_windows >= 26.820.60940 <= 26.1002.52244`
- `codex_desktop_for_windows_microsoft_store_msix_package >= 26.820.7780.0 <= 26.1002.7124.0`

## Remediation
