Snipe-IT is an IT asset/license management system. Prior to 8.6.3, a company-scoped user in FMCS floater mode can access users whose company_id is null because broad API queries and bulk web actions do not consistently apply isCurrentUserHasAccess. The /api/v1/users and /api/v1/users/{id}/licenses endpoints can expose personal data and assigned licenses, /users/bulkeditsave can modify out-of-scope profiles, and /users/merge can soft-delete users and transfer assigned assets. This issue is fixed in version 8.6.3.

### Impact Due to inconsistent authorization checks, a company-scoped user can bypass tenant boundaries to read, mutate, and soft-delete users who do not belong to any company (company_id = null). While direct instance authorization (isCurrentUserHasAccess) correctly denies access to these out-of-scope users, multiple API endpoints and bulk action web routes fail to enforce this restriction, relying instead on class-level permissions or broad scoped queries. Impact: A malicious user scoped to a specific company (e.g., Company A) can: Data Leakage: Extract PII and assigned licenses of users outside their tenant via the API (/api/v1/users and `/api/v1/users/{id}/licenses)`. Data Modification: Mutate out-of-scope user profiles (e.g., changing city, notes) via the /users/bulkeditsave web route. Data Deletion & Asset Theft: Soft-delete out-of-scope users and transfer their assigned assets to themselves via the /users/merge web route. ### Patches Patched in https://github.com/grokability/snipe-it/commit/fbe05a8df4742729a9b0756c016d45f48246cc7b,
