Aliases CVE-2026-55479
Summary Snipe-IT has incorrect permission for legacy license checkin API ### Impact 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.
