Flatpak 1.10.2 isn’t a big update, but it’s here to address a security vulnerability that could lead to potential attacks where a Flatpak app could gain access to files on the host operating system via a custom formatted .desktop file.
This release also fixes some memory leaks and includes various test fixes, and includes a fix for an issue with X11 cookies on the openSUSE Linux operating system. Therefore, it is highly recommended that you update your Flatpak installations to version 1.10.2 as soon as it lands in the your distro’s stable repositories.
