CVE-2026-55516 is an insecure direct object reference vulnerability in Snipe-IT prior to version 8.6.2 affecting the maintenance update API endpoint. When processing PATCH or PUT requests to the maintenance record update route, the application verifies access to the existing maintenance record and its currently associated asset, but then populates attacker-controlled fields from the request, including asset_id, without re-authorizing access to the newly supplied asset. As a result, an authenticated user with permission to update a maintenance record can reassign that record to an asset outside their authorized company scope in multi-company environments, violating intended authorization boundaries and compromising maintenance data integrity.
