Please use GitHub's Private Vulnerability Reporting (Security tab → "Report a vulnerability") on this repository. Do not open public issues for security reports.
sci-nodes provides numeric filter/resample nodes only; it does not execute code embedded in graph definitions. Note that the host runtimes it plugs into (the nonoha engine and embedded runtime) may include script nodes with their own threat model — see the security policy of the host project for loading untrusted graphs.
Security fixes target the latest minor release.
