## Description:
This update for flatpak fixes the following issues:
* CVE-2026-34078: Arbitrary code execution via crafted symlinks in sandbox-
expose options (bsc#1261769).
* CVE-2026-34079: Arbitrary file deletion on host via improper cache file path
validation (bsc#1261770).
* CVE-2026-90616: missing symlink protection allows a malicious sandboxed app
to obtain arbitrary read and write access to files on the host
(bsc#1280236).
* CVE-2026-92162: path traversal via unvalidated `arch` parameter in
`DeployAppstream` (bsc#1282514).
* CVE-2026-96275: arbitrary write access as root via extra-data extraction
(bsc#1282515).
* CVE-2026-96276: arbitrary write in host context via `flatpak build-init`
(bsc#1282516).
* CVE-2026-96280: buffer overflow in OCI delta stream path names
(bsc#1282518).
* CVE-2026-96281: unprivileged active user can bypass anti-downgrade checks
for system apps/runtimes (bsc#1282519).
* CVE-2026-96282: extension metadata path traversal file existence oracle
(bsc#1282520).
* CVE-2026-96807: fixed-filename writes to arbitrary locations via symlink
attack on `.ld.so` (bsc#1282523).
* CVE-2026-96808: `revokefs` symlink path traversal allows local privilege
escalation via commit tampering (bsc#1282524).
Changes for flatpak:
* Update to version 1.16.6 (jsc#PED-17048):
* Fix file descriptor leaks affecting Chromium-based browsers.
* Fix installing extra-data without a runtime, including OpenH264.
* Ignore unusable sandbox-expose paths for portal sub-sandboxes, fixing
Epiphany regressions.
* Fix installed tests and handling of standard file descriptors passed as
invalid flatpak run arguments.
* Switch from Autotools to Meson, preserving system bubblewrap, xdg-dbus-
proxy, curl and distribution-specific installation paths.
* Require bubblewrap >= 0.10.0 and GPGME >= 1.8.0; add Meson, gettext, gtk-doc
and polkit-agent build dependencies and drop obsolete intltool and libelf
build dependencies.
* Generate the system-user pre-script from the Meson build directory and
package the tmpfiles configuration and renamed manual pages.
