Description
Impact
A cross-tenant data injection vulnerability was identified in the Snipe-IT Accessories API when Full Multiple Companies Support (FMCS) is enabled. A low-privileged authenticated user belonging to one company can create an accessory record under another company by supplying a foreign company_id value in the API request body.
The issue occurs because the API create path mass-assigns request parameters directly to the Accessory model, and the Accessory model allows company_id to be mass assigned. Unlike the web controller, which uses Company::getIdForCurrentUser() to enforce the authenticated user’s company context, the API controller does not apply equivalent tenant enforcement during accessory creation.
As a result, a Company A user can inject persistent accessory records into Company B. The injected records are then visible to Company B users as legitimate Company B inventory records. This breaks the integrity of company-scoped inventory data and represents a tenant isolation failure in the accessory creation flow.

Weakness
CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
How to prevent it
- Requirements: Programming languages and supporting technologies might be chosen which are not subject to these issues.
- Implementation: Utilize an appropriate mix of allowlist and denylist parsing to filter control-plane syntax from all input.
