On this page
MongoDB Database Tools mongorestore inconsistently handles the system.buckets. prefix when validating collection names in an untrusted dump. A specially crafted collection name can bypass special-collection guards and operator namespace filters, causing a restore to create an unauthorized user-chosen database account, including an account with the root role. Exploitation requires an operator to restore unauthorized user-controlled data using credentials with sufficient user-management privileges on the destination deployment. Excluding the admin namespace alone does not prevent this behavior. This issue affects MongoDB Database Tools versions 100.4.0 through versions before 100.20.1.

Red Hat
Red Hat rates this Important.
This vulnerability is rated as Important severity because successful exploitation allows an attacker to achieve full administrative control over the destination database, balanced against the prerequisite of an operator restoring untrusted archive data using privileged credentials. In Red Hat environments that package MongoDB tools, such as containerized storage components, `mongorestore` operates as a client-side command-line utility rather than a continuously listening network service. Exposure is therefore restricted to operational workflows where an administrator ingests unverified backup files using destination credentials endowed with user-management permissions.
