## Technical details

The vulnerability is an incorrect authorization flaw (CWE-863) in Snipe-IT's legacy single-seat license checkin flow. The endpoint checks for the "checkout" permission when it should check for "checkin" permission, allowing privilege escalation. An authenticated user with license assignment rights but without unassignment rights can directly access the old checkin endpoint to reclaim license seats from other users or assets. The attack requires network access and a low-privileged authenticated account; no user interaction is needed. The vulnerability is fixed in version 8.6.2.
