Description
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.
