## How to fix

- Fixed in Build 6301

## Technical details

An object-level authorization vulnerability in the Windows DNS zone-scope deletion API fails to validate whether the authenticated user is authorized to manage the requested zone. An authenticated non-administrative operator can supply an arbitrary zone identifier and delete zones outside their assigned scope, bypassing both administrator privilege checks and user-to-zone mappings. The fix enforces mandatory authorization checks and validates user scope before processing zone deletion.
