CVE-2026-97024Network attack vectorHinoki check available

Host file destruction via unchecked deploy symlink

Published Sep 29, 2026 · Updated Sep 29, 2026

Symlink-following in Flatpak on Red Hat Enterprise Linux 7 through 10 allows remote attackers to empty host files during app deployment. Flatpak's runtime deploy path checks the files directory but follows an unchecked files/etc symlink while replacing passwd, group, machine-id, or resolv.conf. A victim must install or upgrade the malicious app; system-wide deployment performs the file operations as root, and attacker-chosen replacement content is not established.
