If a path resembles a CLI flag, editors like Vim may interpret it as a command, potentially causing unintended file overwrites or command execution. ### Impact #### Direct `launch-editor` users Only apps that match all of the following conditions are affected: - The attacker is able to create a file system entry (e.g. a file or directory) starting with `+` or `-` in the working directory - The user uses or the app specifies any of the following editors: - Vim (including gVim) - MacVim - Emacs (including Emacsclient) - Notepad++ (only if using a plugin exposing dangerous operations via plugin messages) - The first argument of `launchEditor` can start with `+` or `-` or the user is using WSL #### `launch-editor-middleware` users Only apps that match the following conditions are affected: - The attacker is able to create a file system entry (e.g. a file or directory) starting with `+` or `-` in the working directory - The user uses or the app specifies any of the following editors: - Vim (including gVim) - MacVim - Emacs (including Emacsclient) - Notepad++ (only if using a plugin exposing dangerous operations via plugin messages) - launch-editor older than v2.2.0 is used, or the user is using WSL #### Vite users Only apps that match the following conditions are affected: - The attacker is able to create a file system entry (e.g. a file or directory) starting with `+` or `-` in the working ",
