{"id":"CVE-2026-111253","summary":"Dnf5daemon-server: dnf5: dnf5daemon-server: missing session-owner check allows foreign d-bus callers to replace another client's resolved transaction","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":"2026-11-05T21:31:40.180797084Z","published":"2026-11-05T16:30:05.133Z","database_specific":{"cna_assigner":"fedora","cwe_ids":["CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111253.json"},"references":[{"type":"WEB","url":"https://access.redhat.com/downloads/content/package-browser/"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-111253"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2553683"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111253.json"},{"type":"FIX","url":"https://github.com/rpm-software-management/dnf5/commit/46a4a8ad8d34af91ec2add6bb29e487571ea6c85"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-111253"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/rpm-software-management/dnf5","events":[{"introduced":"0"},{"fixed":"46a4a8ad8d34af91ec2add6bb29e487571ea6c85"}],"database_specific":{"extracted_events":[{"source":"REFERENCES_COMMIT","range":[{"fixed":"46a4a8ad8d34af91ec2add6bb29e487571ea6c85"}]}]}}],"versions":["5.4.6.0","5.4.5.0","5.4.4.0","5.4.3.0","5.4.2.1","5.4.2.0","5.4.1.0","5.4.0.0","5.2.17.0","5.3.0.0","5.2.16.0","5.2.15.0","5.2.14.0","5.2.13.1","5.2.13.0","5.2.12.0","5.2.11.0","5.2.10.0","5.2.9.0","5.2.8.1","5.2.8.0","5.2.7.0","5.2.6.2","5.2.6.1","5.2.6.0","5.2.5.0","5.2.4.0","5.2.3.0","5.2.2.0","5.2.1.0","5.2.0.0","5.1.17","5.1.16","5.1.15","5.1.14","5.1.13","5.1.12","5.1.11","5.1.10","5.1.9","5.1.8","5.1.7","5.1.6","5.1.5","5.1.4","5.1.3","5.1.2","5.1.1","5.1.0","5.0.15","5.0.14","5.0.13","5.0.12","5.0.11","5.0.10","5.0.9","5.0.7","5.0.5","5.0.3","5.0.2","5.0.1","5.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/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"}]}
