What is CVE-2025-49143?

CVE-2025-49143 is a medium-severity missing authorization vulnerability in nautobot, published on 10 Jun 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

Nautobot is a Network Source of Truth and Network Automation Platform. Prior to v2.4.10 and v1.6.32 , files uploaded by users to Nautobot's MEDIA_ROOT directory, including DeviceType image attachments as well as images attached to a Location, Device, or Rack, are served to users via a URL endpoint that was not enforcing user authentication. As a consequence, such files can be retrieved by anonymous users who know or can guess the correct URL for a given file. Nautobot v2.4.10 and v1.6.32 address this issue by adding enforcement of Nautobot user authentication to this endpoint.

Weakness: CWE-200
