Overview
Affected versions of this package are vulnerable to Missing Authorization in the web UI handlers responsible for managing hosts and networks. An attacker can gain unauthorized access to sensitive information and perform destructive actions across resources owned by other operators by sending crafted requests to endpoints such as /ui/hosts/{id}/block, /ui/hosts/{id}, /ui/hosts, and /ui/networks. This is only exploitable if at least one non-admin operator exists in the deployment (such as when self-registration or OIDC is enabled, or an admin has created additional operators).
