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.","cvssScore":6.6,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:H/A:H","cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-111253","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2553683","tags":[]},{"url":"https://github.com/rpm-software-management/dnf5/commit/46a4a8ad8d34af91ec2add6bb29e487571ea6c85","tags":[]}],"exploitRefs":[{"url":"https://github.com/rpm-software-management/dnf5/commit/46a4a8ad8d34af91ec2add6bb29e487571ea6c85","tags":[]}],"hasPoc":true,"ai":null}
