Changes:
 flatpak (1.16.6-1~deb13u1) trixie-security; urgency=high
 .
   * Backport new upstream stable release for Debian 13
     - Fix a sandbox escape involving symlinks passed to flatpak-portal.
       A malicious or compromised Flatpak app could exploit this to achieve
       arbitrary code execution on the host.
       (CVE-2026-34078, GHSA-cc2q-qc34-jprg) (Closes: #1132943)
     - Prevent arbitrary file deletion outside the sandbox by a malicious or
       compromised Flatpak app
       (CVE-2026-34079, GHSA-p29x-r292-46pp) (Closes: #1132944)
     - Prevent a local user from reading any file that is readable by the
       _flatpak system user. A mitigation is that it would be very unusual
       for these files not to be readable by the original local user as well.
       (No CVE ID, GHSA-2fxp-43j9-pwvc) (Closes: #1132946)
     - Prevent a local user from making another local user unable to cancel
       an ongoing download of apps or runtimes installed system-wide
       via the system helper.
       (No CVE ID, GHSA-89xm-3m96-w3jg) (Closes: #1132945)
     - Various fixes for regressions caused when fixing CVE-2026-34078
   * Revert changes that are not appropriate for a stable update:
     - Revert "d/watch: Convert to v5 format, only watch stable
       (even-numbered) releases"
     - Revert "Standards-Version: 4.7.3"
