A corrective update for the Flatpak 1.10.2 framework is available, which addresses a vulnerability (CVE-2021-21381) that allows the package author of an application to bypass the established sandbox isolation and gain access to files in the host system. The issue appears starting from the 0.9.4 release. <\/p>\n

The vulnerability is caused by an error in the implementation of the file forwarding function, which allows manipulation of the .desktop file to access resources in an external file system that the running application is prohibited from accessing. When files with tags '@@' and '@@u' are added in the Exec field, flatpak considers 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 creators of malicious packages to establish access to external files, despite the appearance of running in isolation mode.
