CVE-2026-111253 Dnf5daemon-server: dnf5: dnf5daemon-server: missing session-owner check allows foreign d-bus callers to replace another client's resolved transaction
Description
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.
