Technical details
The mongorestore tool inconsistently validates the system.buckets. prefix when processing collection names, allowing specially crafted names to bypass namespace filters and special-collection guards. An unauthenticated attacker can exploit this by providing a malicious dump file; when restored by a privileged operator, unauthorized user accounts with elevated roles (including root) can be created. The vulnerability affects versions 100.4.0 through 100.20.0.
