Subject: bug#48676: Arbitrary code execution in Org export macros

Hi Glenn,
     The definition for local variables doesn't cover things like org
macros, though the spirit of the policy is something worth keeping in
mind. Running M-x org-export-dispatch and hitting two keys means that
the user has to do something to trigger code execution, much like they
would have to intentionally accept certain risky local variables.

That said, the fact that many org operations can run arbitrary code is
definitely something that needs clearer documentation. It might make
sense to add a setting to detect closures that appear in org files to
ask for permission before running, but it likely should not be on by

For a fairly extensive discussion of code execution in org see this
thread from Nov 2020.
