Which has an obligation to accept and carry out UN Security Council Resolutions?

Under the UN Charter, all United Nations member states are obligated to accept and carry out decisions of the UN Security Council. Sanctions and Compliance Domains emphasize that UN Security Council Resolutions issued under Chapter VII are binding on all UN members, not just Security Council members or targeted states.

Only member states have this obligation. Permanent membership or targeted status does not change the scope of obligation.
