Snipe-IT Vulnerable to Unauthorized Asset Request Cancellation via Unguarded cancel_by_admin Parameter
Impact
The route POST /account/request/{itemType}/{itemId}/{cancel_by_admin?}/{requestingUser?} accepts cancel_by_admin as a plain URL path segment with no authorization check. Any authenticated user regardless of permissions can set this parameter to a truthy value and supply a victim's user ID to silently cancel that user's pending asset requests. The attacker only needs an active session; no elevated privilege is required.
