{"id":"DEBIAN-CVE-2026-97024","details":"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.","modified":"2026-09-29T07:00:10.478854177Z","published":"2026-09-29T04:18:02.397Z","upstream":["CVE-2026-97024"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-97024"}],"affected":[{"package":{"name":"flatpak","ecosystem":"Debian:12","purl":"pkg:deb/debian/flatpak?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.14.10-1","1.14.10-1~deb12u1","1.14.10-1~deb12u2","1.14.4-1","1.14.4-1+deb12u1","1.14.4-1+deb12u1~bpo11+1","1.14.4-2","1.14.5-1","1.14.6-1","1.14.6-1~deb13u1","1.14.8-1","1.14.8-1~deb12u1","1.15.0-1","1.15.0-2","1.15.1-1","1.15.10-1","1.15.12-1","1.15.2-1","1.15.3-1","1.15.4-1","1.15.6-1","1.15.7-1","1.15.8-1","1.15.9-1","1.15.91-1","1.16.0-1","1.16.0-2","1.16.0-2~bpo12+1","1.16.1-1","1.16.1-1~bpo12+1","1.16.1-2","1.16.1-3","1.16.2-1","1.16.2-1~deb13u1","1.16.3-1","1.16.3-1~deb13u1","1.16.4-1","1.16.4-2","1.16.5-1","1.16.6-1","1.16.6-1~deb13u1","1.16.6-1~deb13u1~bpo12+1","1.16.6-1~deb13u2","1.16.6-1~deb13u3","1.17.2-1","1.17.3-1","1.17.3-2","1.17.6-1","1.18.0-1","1.18.1-1","1.18.2-1","1.18.3-1","1.18.4-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-97024.json"}},{"package":{"name":"flatpak","ecosystem":"Debian:13","purl":"pkg:deb/debian/flatpak?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.16.6-1~deb13u3"}]}],"versions":["1.16.1-1","1.16.1-2","1.16.1-3","1.16.2-1","1.16.2-1~deb13u1","1.16.3-1","1.16.3-1~deb13u1","1.16.4-1","1.16.4-2","1.16.5-1","1.16.6-1~deb13u1","1.16.6-1~deb13u1~bpo12+1","1.16.6-1~deb13u2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-97024.json"}},{"package":{"name":"flatpak","ecosystem":"Debian:14","purl":"pkg:deb/debian/flatpak?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.16.1-1","1.16.1-2","1.16.1-3","1.16.2-1","1.16.2-1~deb13u1","1.16.3-1","1.16.3-1~deb13u1","1.16.4-1","1.16.4-2","1.16.5-1","1.16.6-1","1.16.6-1~deb13u1","1.16.6-1~deb13u1~bpo12+1","1.16.6-1~deb13u2","1.16.6-1~deb13u3","1.17.2-1","1.17.3-1","1.17.3-2","1.17.6-1","1.18.0-1","1.18.1-1","1.18.2-1","1.18.3-1","1.18.4-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-97024.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H"}]}
