Title

Flatpak: flatpak: arbitrary file deletion in root context via path traversal in deploy directory export/bin

Summary

A path traversal vulnerability in Flatpak's handling of the export/bin directory during app deployment allows a malicious Flatpak app to cause deletion of attacker-chosen files outside the deployment directory when the app is installed or upgraded. In system-wide installations, the deletion is performed as root.
