pip show nautobot

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2025-49143, inspect your installed packages using pip:

pip show nautobot

Analyze the terminal output to locate any version of Nautobot in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.6.32), your application is affected.

Note: The pip show nautobot command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Nautobot, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact 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. For DeviceType image attachments, a mitigating factor is that no URL endpoint exists for listing the contents of the `devicetype-images/` subdirectory, and the file names are as specified by the uploading user, so any given DeviceType image attachment can only be retrieved by correctly guessing its file name. Similarly, for all other image attachments, while the images *can* be listed by accessing the `/api/extras/image-attachments/` endpoint *as an authenticated user only*, absent that authenticated access, accessing the files would again require guessing file names correctly. ### Patches Nautobot v2.4.10 and v1.6.32 will address this issue by adding enforcement of Nautobot user authentication to this endpoint. ### Workarounds No workaround other than applying the patch given in https://github.com/nautobot/nautobot/pull/6672 (2.x) or https://github.com/nautobot/nautobot/pull/6703 (1.6) ### References _Are there any links users can visit to find out more?_ - https://github.com/nautobot/nautobot/commit/9c892dc300429948a4714f743c9c2879d8987340 - https://github.com/nautobot/nautobot/commit/d99a53b065129cff3a0fa9abe7355a9ef1ad4c95
