{"id":"DEBIAN-CVE-2026-107466","details":"A flaw was found in flatpak-builder. This vulnerability allows an attacker to cause information disclosure by convincing a user or continuous integration (CI) system to process a crafted build manifest. By specifying local file Uniform Resource Identifiers (URIs) within source download definitions, the builder bypasses directory confinement checks. As a result, sensitive host files accessible to the build process can be read and incorporated into the build artifacts.","modified":"2026-10-09T12:00:14.881702918Z","published":"2026-10-08T08:16:34.193Z","upstream":["CVE-2026-107466"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-107466"}],"affected":[{"package":{"name":"flatpak-builder","ecosystem":"Debian:12","purl":"pkg:deb/debian/flatpak-builder?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.3-1","1.3.1-1","1.3.3-1","1.3.4-1","1.3.5-1","1.4.0-1","1.4.1-1","1.4.10-1","1.4.11-1","1.4.12-1","1.4.12-2","1.4.2-1","1.4.4-1","1.4.4-1~bpo12+1","1.4.4-2","1.4.5-1","1.4.6-1","1.4.6-2","1.4.7-1","1.4.8-1","1.4.9-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-107466.json"}},{"package":{"name":"flatpak-builder","ecosystem":"Debian:13","purl":"pkg:deb/debian/flatpak-builder?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.10-1","1.4.11-1","1.4.12-1","1.4.12-2","1.4.4-2","1.4.5-1","1.4.6-1","1.4.6-2","1.4.7-1","1.4.8-1","1.4.9-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-107466.json"}},{"package":{"name":"flatpak-builder","ecosystem":"Debian:14","purl":"pkg:deb/debian/flatpak-builder?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.4.11-1"}]}],"versions":["1.4.10-1","1.4.4-2","1.4.5-1","1.4.6-1","1.4.6-2","1.4.7-1","1.4.8-1","1.4.9-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-107466.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N"}]}
