CVE-2020-14001 - High Severity Vulnerability
kramdown is yet-another-markdown-parser but fast, pure Ruby, using a strict syntax definition and supporting several common extensions.
Library home page: https://rubygems.org/gems/kramdown-2.1.0.gem
Dependency Hierarchy: - jekyll-sitemap-1.4.0.gem (Root Library) - jekyll-4.0.0.gem - :x: **kramdown-2.1.0.gem** (Vulnerable Library)
Found in HEAD commit: 5d38d3ad312d98971fd293b26516b651ba7c3479
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.
