How did you install Prowler?
Cloning the repository from github.com (git clone)
Environment Resource
I've reproduced this issue when run as a CronJob in my homelab minikube cluster, as a local docker container, and built from source from a github clone.
OS used
MacOS (local)
Debian Bookworm (container)
Prowler version
Prowler 5.23.0 (You are running the latest version, yay!)
Python version
Python 3.12.12
Pip version
uv 0.10.9 (f675560f3 2026-03-06)
Context
This is the same code path added in PR #10470 (fix for #10457). The --registry flag itself works correctly, but --registry-list was never tested end-to-end. The root cause is that ImageProvider.init returns early when _listing_only is set (line 167), skipping Provider.set_global_provider(self) at the bottom of the constructor. main.py:294 then calls print_credentials() on None.
I have a fix ready with a regression test. PR incoming shortly.
