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