What is CVE-2025-49143?

Nautobot, a Network Source of Truth and Network Automation Platform, contains a vulnerability that allows unauthorized access to files uploaded by users to its MEDIA_ROOT directory. Specifically, prior to versions 2.4.10 and 1.6.32, images related to DeviceTypes and other entities could be accessed directly without proper user authentication. This flaw poses a significant risk, as anonymous users might exploit this issue to retrieve sensitive files simply by knowing or guessing the URL. Versions 2.4.10 and 1.6.32 have addressed this security gap by ensuring user authentication checks are enforced on the endpoint serving these files.
