CVE-2026-54329
Snipe-IT API Vulnerable to Cross-Tenant Accessory Injection
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. ### Patches Patched in https://github.com/grokability/snipe-it/commit/dc8cbf4786bb38b260b4ae1723ec9e7f81d82fe5
