CVE-2026-55703Public exploitNetwork attack vector

Authenticated maintenance record disclosure via missing authorization

Published Aug 19, 2026 · Updated Aug 19, 2026

Missing authorization in Snipe-IT before 8.6.3 allows remote authenticated users to read maintenance records via /maintenances/{id}. MaintenancesController::show() renders the maintenance view with a bound Maintenance object and omits the asset-view authorization check that sibling actions enforce. Any activated account in the same company can reuse or enumerate maintenance IDs to expose asset tags, suppliers, purchase costs, notes, and dates, while company-scoped binding still blocks cross-company reads.
