Summary

The flaw in dnf5daemon-server affects Red Hat Hardened Images. Session methods on dynamically exported D-Bus session objects do not check that the caller is the unique sender that created the session (CWE-862). A local attacker can modify another user's live package-management session and replace its resolved transaction plan, and if the legitimate party later authorizes execution, the root daemon may apply the attacker-chosen package operations.
