CVE-2026-97024: Flatpak path traversal in files/etc directory during app deployment

CVE-2026-97024 · Severity: high · CVSS 7.1 · Published 2026-09-29

Flatpak, a system for sandboxing and distributing desktop applications, contains a flaw that allows a malicious app to corrupt or replace critical host system files such as password files and DNS configuration during installation. When a system administrator installs a compromised app, these essential files can be emptied or redirected to attacker-controlled content, potentially rendering the system unusable or compromising user authentication and network connectivity.

Technologies: Flatpak. Vendors: Flatpak.

Technical details

A path traversal vulnerability in Flatpak's deployment logic fails to validate symlinks when processing the files/etc directory, allowing a malicious Flatpak manifest to write arbitrary content to host system paths with the privileges of the installing user (root in system-wide deployments). The attack requires user interaction to install or upgrade the app and leverages CWE-61 (insecure symlink following). The vulnerability affects the integrity and availability of critical system files, and patches are available from Flatpak upstream.
