Technical details
An authorization bypass in the provisioning files API fails to properly validate folder-level permissions when handling Git Sync provisioned resources. A user with edit access to one folder can use the API to modify or delete resources in folders where they possess only view access, bypassing intended access controls. The vulnerability requires an authenticated user with edit permissions in at least one folder.
