A vulnerability was detected in HKUDS nanobot up to 0.2.1. The affected element is the function connect_mcp_servers of the file nanobot/agent/tools/mcp.py of the component MCP enabledTools Scope Handler. Performing a manipulation results in improper access controls. The attack is possible to be carried out remotely. The exploit is now public and may be used. Upgrading to version 0.3.0 is sufficient to fix this issue. The patch is named 4436. You should upgrade the affected component. Multiple issues were reported to the project. They reacted with a high level of professionalism and kindness: "Both reports describe the same root cause: MCP resource and prompt wrappers could be registered outside the intended enabledTools scope. The registration boundary was corrected".
