The kramdown gem before 2.3.0 for Ruby processes the template option inside
Kramdown documents by default, which allows unintended read access (such as
template=“/etc/passwd”) or unintended embedded Ruby code execution (such as
a string that begins with template="string://<%= `). NOTE: kramdown is used
in Jekyll, GitLab Pages, GitHub Pages, and Thredded Forum.
