The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. in versions before 1.10.9, 1.12.9, 1.14.6, and 1.15.8, a malicious or compromised Flatpak app could execute arbitrary code outside its sandbox. Normally, the --command
argument of flatpak run
expects to be given a command to run in the specified Flatpak app, optionally along with some arguments. However it is possible to instead pass bwrap
arguments to --command=
, such as --bind
. It's possible to pass an arbitrary commandline
to the portal interface org.freedesktop.portal.Background.RequestBackground
from within a Flatpak app. When this is converted into a --command
and arguments, it achieves the same effect of passing arguments directly to bwrap
, and thus can be used for a sandbox escape. The solution is to pass the --
argument to bwrap
, which makes it stop processing options. This has been supported since bubblewrap 0.3.0. All supported versions of Flatpak require at least that version of bubblewrap. xdg-desktop-portal version 1.18.4 will mitigate this vulnerability by only allowing Flatpak apps to create .desktop files for commands that do not start with --. The vulnerability is patched in 1.15.8, 1.10.9, 1.12.9, and 1.14.6.
