Security Fix(es):

A malicious Flatpak extension can probe the host filesystem to determine what files and directories exist at arbitrary paths, and host directory listings can be disclosed to sandboxed applications using the extension. Additionally, unvalidated extension metadata can cause extension content to be mounted at unintended locations inside the sandbox.(CVE-2026-96282)

By calling org.freedesktop.Flatpak.SystemHelper.CancelPull on another user&apos;s pull, the pull is not actually cancelled but removed from internal tracking, making it impossible for the owning user to stop it. Ongoing pulls cannot be stopped.(CVE-2026-96283)</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for flatpak is now available for openEuler-20.03-LTS-SP4/openEuler-24.03-LTS-SP3.
