Imported Agents Become Server Commands in Paperclip

Paperclip breaks the normal boundary between configuration and execution. A user who should only be able to import an agent can end up making the server run host commands, and the local_trusted mode flaw lets the same thing reach developer machines through a browser. Oasis Security found CVE-2026-41679 in authenticated deployments and a second critical path in local_trusted mode. The first flaw turns self-registration into a persistent board-level API key, then uses that key to reach an import route that trusts board-level access too much; the second lets a browser-originated request import and wake a malicious agent on the host. A third access-control flaw exposed control-plane data, and Rapid7 has already released a Metasploit module for CVE-2026-41679. The practical risk is wider than one product bug. Any AI agent control plane that treats imported workflows or agents as safe input can hand execution to lower-privilege users, and patching only closes the entry point, not the need to review what registration and import trust in the first place.
