Hey everyone,
I just set up a self-hosted GitHub Actions runner in my homelab and wrote about it in my self-hosted blog! This is my second blog entry, so I would really appreciate any feedback or suggestions to help improve my writing is more than welcome.

I think it was when you create a merge request back, that the original repo would then run the forked branch on the original runners.
From what I can tell, its now been much more locked down, so its better, but still worth being careful about.

The other potential risk is that the github action author maliciously modifies their code in a later version, but that is solved with version pinning the actions.
