The server is designed for local-first use and incorporates robust input validation (`sanitizePath`, `validateFilename`) in the notebook component to mitigate path traversal and similar file-system based vulnerabilities when executing user-defined code. External process execution (`spawn` for Node.js, npm, tsx) is performed with explicit commands and arguments, reducing the risk of shell injection. There are no overt hardcoded secrets. While the Observatory component allows for flexible CORS configuration (including `*`), this is an opt-in setting in an optional, typically local, monitoring tool. Overall, the source code indicates a conscious effort towards security for its intended use case.
