CVE-2026-55479: Snipe-IT has incorrect permission for legacy license checkin API

August 28, 2026

The legacy single-seat license checkin flow authorizes the action with the checkout permission instead of the checkin permission. Because of this, a user who is allowed to assign licenses but not unassign them can still directly access the old checkin endpoint and reclaim a license seat that is currently assigned to another user or asset.
