CVE-2026-96282 Flatpak: flatpak: extension metadata path traversal file existence oracle

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.
