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.

For various versions of Bitbucket, there is an authenticated command injection vulnerability that can be exploited by injecting environment variables into a user name. This module achieves remote code execution as the atlbitbucket user by injecting the GIT_EXTERNAL_DIFF environment variable, a null character as a delimiter, and arbitrary code into a user's user name. The value (payload) of the GIT_EXTERNAL_DIFF environment variable will be run once the Bitbucket application is coerced into generating a diff. This Metasploit module requires at least admin credentials, as admins and above only have the option to change their user name.
