Nautobot is a Network Source of Truth and Network Automation Platform. Prior to 2.4.37 and 3.1.8, a user with extras.add_relationship or extras.change_relationship permission can store HTML or JavaScript in a Relationship description, and a user with dcim.add_modulefamily or dcim.change_modulefamily permission can store it in a Module Family name. Nautobot assigns these values to form field help_text rendered by render_field.html through Django's |safe filter without adequate neutralization. The stored content executes in the authenticated browser session of any user, including an administrator or superuser, who opens an affected create or edit form. This can enable actions as the victim, session or token theft, and further privilege escalation. This issue is fixed in versions 2.4.37 and 3.1.8.
