Overview

Jinja2 is a template engine written in pure Python. It provides a Django inspired non-XML syntax but supports inline expressions and an optional sandboxed environment.

Affected versions of this package are vulnerable to Sandbox Bypass. Users were allowed to insert str.format through web templates, leading to an escape from sandbox.
