Official description

InvenTree is an Open Source Inventory Management System.

The vulnerability has been addressed as follows: 1. HTML sanitization has been enabled in the front-end markdown rendering library - `easymde`. 2. Stored markdown is also validated on the backend, to ensure that malicious markdown is not stored in the database. These changes are available in release versions 0.16.5 and later.
