Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. In versions prior to 1.10.8, 1.12.8, 1.14.4, and 1.15.4, if an attacker publishes a Flatpak app with elevated permissions, they can hide those permissions from users of the `flatpak(1)` command-line interface by setting other permissions to crafted values that contain non-printable control characters such as `ESC`. A fix is available in versions 1.10.8, 1.12.8, 1.14.4, and 1.15.4. As a workaround, use a GUI like GNOME Software rather than the command-line interface, or only install apps whose maintainers you trust. https://github.com/flatpak/flatpak/commit/6cac99dafe6003c8a4bd5666341c217876536869 https://github.com/flatpak/flatpak/commit/7fe63f2e8f1fd2dafc31d45154cf0b191ebec66c https://github.com/flatpak/flatpak/commit/409e34187de2b2b2c4ef34c79f417be698830f6c https://github.com/flatpak/flatpak/security/advisories/GHSA-h43h-fwqx-mpp8
