This seems to be a potentially breaking change (from security perspective), and has to be documented? |

There was a problem hiding this comment.
In the comment could you explain the purpose of setting the entitlement by default?

It is not. The default networking for build step containers if builder was in container was already host (meaning host inside the container, not host of machine) and will remain like this in v0.13. This was without setting any |

--allow network.host on a plain 'docker build' invocation only works if the runner's Docker daemon was separately started with --allow-insecure-entitlement network.host -- an infrastructure-level flag this workflow doesn't control. The docker-container builder driver has had network.host entitlement enabled by default since buildx v0.13 (docker/buildx#2266), with no daemon-side dependency, so add an explicit docker/setup-buildx-action step and switch from 'docker build' to 'docker buildx build --load' for this scan step. Addresses the review finding that the entitlement flag's actual effect was asserted, not verified, on the plain docker driver.
