{"id":"DEBIAN-CVE-2026-111253","details":"A flaw was found in dnf5daemon-server. Session methods on dynamically exported D-Bus session objects do not verify that the caller is the unique sender that created the session. A local attacker can modify another user's live package-management session and replace its resolved transaction plan. If the legitimate session party later authorizes execution, the root daemon may apply the attacker-chosen package operations.","modified":"2026-11-06T21:00:06.778115282Z","published":"2026-11-05T17:17:37.623Z","upstream":["CVE-2026-111253"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-111253"}],"affected":[{"package":{"name":"dnf5","ecosystem":"Debian:14","purl":"pkg:deb/debian/dnf5?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.3.0.0-1","5.3.0.0-2","5.4.0.0-1","5.4.2.0-1","5.4.2.1-1","5.4.3.0-1","5.4.4.0-1","5.4.5.0-1","5.4.6.0-1","5.4.6.0-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-111253.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:H/A:H"}]}
