CVE-2026-55516 · Severity: high · CVSS 7.7 · Published 2026-07-10

Snipe-IT is an asset management system used by organizations to track and maintain IT equipment across multiple departments or subsidiary companies. In multi-company deployments, this vulnerability allows an authenticated employee from one company to tamper with maintenance records of assets belonging to a different company. An attacker could corrupt maintenance histories, warranty records, and cost tracking data on victim assets, undermining audit compliance and operational integrity.

## Technical details

The vulnerability exists in the API endpoint `PATCH /api/v1/maintenances/{maintenance_id}` (and likely `PUT` variant) in `app/Http/Controllers/Api/MaintenancesController.php`. The application correctly validates that the user has access to the current maintenance record's asset before allowing the update, but then uses `$maintenance->fill($request->all())` and `$maintenance->save()` without re-validating the newly supplied `asset_id` against the user's company scope. Since `asset_id` is fillable on the maintenance model, an authenticated user with maintenance-update permissions can change the asset_id to point to any asset, including those outside their authorized company boundary. The attack requires a valid API token, maintenance-update permission, and access to an existing maintenance record in the user's own company, but does not require access to the target asset. This is a classic authorization-bypass-through-user-controlled-key flaw (CWE-639) that breaks tenant isolation in multi-company environments.
