Package : flatpak
CVE ID : CVE-2026-34078 CVE-2026-34079
Multiple security vulnerabilities were discovered in Flatpak, an
application deployment framework for desktop apps, which could allow a
Flatpak app to delete arbitrary hosts on the host or break out of the
sandbox resulting in code execution in the host context.
For the stable distribution (trixie), these problems have been fixed in
version 1.16.6-1~deb13u1.
We recommend that you upgrade your flatpak packages.
