Impact
All users of mjml-python who insert untrusted data into mjml templates unless that data is checked in a very strict manner. User input like
<script>would be rendered as<script>in the final HTML output.The attacker must be able to control some data which is later injected in an mjml template which is then send out as email to other users. The attacker could control contents of email messages sent through the platform.
