@kbn/security-hardening

A package counterpart of src/setup_node_env/harden - containing overrides, utilities, and tools to reduce potential vulnerability.

console

When running in production mode (process.env.NODE_ENV === 'production'), global console methods debug, error, info, log, trace, and warn are overridden to implement input sanitization. The export unsafeConsole provides access to the unmodified global console methods.

prototype

The prototypes of most built-in classes are sealed to mitigate many prototype pollution vulnerabilities.
