Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
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. Check out the EPSS documentation for more details.

to version 1.10.9, 1.12.9, 1.14.6, 1.15.8 or higher.
Affected versions of this package are vulnerable to Argument Injection in long option names passed to the xdg-desktop-portal
interface org.freedesktop.portal.Background.RequestBackground
, leading to sandbox escape. An attacker can have additional commands executed that would normally not be allowed by passing them into a long option argument inside a --command
argument, e.g. flatpak run --command=--bind org.gnome.gedit / /host ls -l /host
.
This is also exploitable by passing malicious arguments directly to flatpak run
.
xdg-desktop-portal
has counteracted this vulnerability by allowing only .desktop
files for commands that do not start with -
. Using a patched version will avoid the vulnerability in flatpak
.
