Vulnerability is caused by an error in the implementation of the file access redirection function (\"file forwarding\"), which allows manipulation with the .desktop file to access resources in an external file system that the running application is prohibited from accessing. When files with the labels \"@@\" and \"@@u\" are added to the Exec field, flatpak will assume that the specified target files have been explicitly indicated by the user and automatically grant access to these files in the sandbox. This vulnerability can be exploited by malicious package authors to gain access to external files, despite the appearance of running in isolation mode.
