Overview
kramdown is a Yet-another-markdown-parser but fast, pure Ruby, using a strict syntax definition and supporting several common extensions.
Affected versions of this package are vulnerable to Remote Code Execution. The gem 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://<%= `).
