Vulnerability details
The vulnerability allows a low-privileged remote attacker to modify user or group relationships without permission to view those users or groups and discover whether they exist.
The vulnerability exists due to missing related-object permission checks when Nautobot processes REST API requests or Import Objects jobs. A low-privileged remote attacker can assign these relationships with appropriate object creation or update permissions despite lacking view_user or view_group permissions.
