MediumCode node loads external modules
The code imports modules, which requires the n8n instance to allow them (NODE_FUNCTION_ALLOW_EXTERNAL/BUILTIN) and widens what the code can do.
Confidence: high · Definite match
Suggested fix: Confirm each module is necessary and allow-listed explicitly on the n8n instance.
