Set the Safe Mode Using the CLI

When Asciidoctor is invoked via the CLI, the safe mode is set to UNSAFE by default.

Assign safe mode level

You can change the security level by executing one of the following commands:

-S, --safe-mode=SAFE_MODE: Sets the safe mode level of the document according to the assigned level (UNSAFE, SAFE, SERVER, SECURE).
--safe, asciidoctor-safe: Sets the safe mode level to SAFE. Provided for compatibility with the python AsciiDoc safe command.

You can also set the safe mode from the API and enable or disable content based on the current safe mode.
