CVE-2026-97024 · Flatpak: flatpak: arbitrary write in root context via path traversal in deploy directory files/etc

This page contains facts from public vulnerability sources. Check the original advisory before updating.

A path traversal vulnerability in Flatpak's handling of the files/etc directory during app deployment allows a malicious Flatpak app to cause certain host system files (such as passwd, group, machine-id, or resolv.conf) to be emptied or replaced with a symlink when the app is installed or upgraded. In system-wide installations, the write is performed as root.
