Deployment Type

Self-hosted

NetBox Version

v4.4.0

Python Version

3.12

Steps to Reproduce

Go to a random site/rack/device, e.g. https://demo.netbox.dev/dcim/racks/1/
Click on "Attach an image"
Select a random image and then enter as the name something that contains a slash, e.g. todays date 9/3/25

Expected Behavior

Image gets added or an error is shown that says can't use a slash in the name.

Observed Behavior

<class 'IndexError'>

list index out of range

which comes from here:

  File "/opt/netbox/netbox/extras/models/models.py", line 731, in filename
    return os.path.basename(self.image.name).split('_', 2)[2]
           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^
IndexError: list index out of range

The new index and code was added in #18990. This is currently preventing us from upgrading to v4.4 as we seem to have image attachments with slashes in their names in the database and on the filesystem (which are even nested into subfolders oO):
