Title
Flatpak: flatpak: world-writable temporary child repositories in system-helper cache path
Summary
Flatpak creates temporary child repository directories under the user cache with world-writable permissions (0777). On multi-user systems with a permissive umask, other local users could read or modify the temporary directory used while installing apps or runtimes, potentially causing installation failures (denial of service); tampered content would fail signature/digest verification rather than being trusted.
Severity
3.9 (Low)
