Same problem with docker scout cves -e fs://. However, getting different behaviors across several environments.

Using Docker Engine v27.1.1 on RHEL 8 x86_64. Docker Scout v1.13.0, get a nil pointer dereference panic.

Strangely, getting different traces in a Jenkins pipeline versus a direct SSH terminal console to that RHEL server. The former shows a raw Go panic trace for a nil pointer deference. The latter shows a nicer error about Docker Hub authentication. Even though docker login claims to succeed.

Not getting any errors when using Docker Desktop on Windows x86_64 and Mac ARM 64 laptops. The Mac is using Docker v27.0.3, Scout v1.10.0.

What's crazy is that I'm not even targeting any images, just local files. It seems that Scout is blindly assuming local images, and only doing so in Linux, with platform specific (tty specific?) error handling logic.

Unfortunately, difficult to track the problem much further due to Docker (Scout) obfuscating the logic as closed source.

When I run docker scout quickview on kubuntu24.04, my computer is running like a crazy (I can hear the sound) but I loose control of my computer from screen. The mouse is not working. The keyboard is not working, either. I am not sure if I have to wait longer or I just restart my computer with bruite-force.

Update:

Docker Scout crashes with v1.13.0. Works fine with v1.12.0. Something is broken in the current release.
