$ docker scout cves ghcr.io/warpstreamlabs/bento:1.4.0-5-gfc76a5647
    i New version 1.16.1 available (installed version is 1.15.1) at https://github.com/docker/scout-cli
          ✓ SBOM of image already cached, 333 packages indexed

LGTM! Appreciate the PR 😄 Am currently looking at using govulncheck in our pipelines to alert us of these issues sooner.
