Summary
Pin the
ghcr.io/hadolint/hadolint:v2.14.0-debianbase image to its immutable OCI digest in the action Dockerfile.Why
The action currently references the hadolint image by tag only:
FROM ghcr.io/hadolint/hadolint:v2.14.0-debianWhile the version tag improves readability, it does not fully guarantee immutability on its own. Pinning the image by digest makes the exact image content explicit and helps reduce supply-chain risk from an unexpected tag retargeting or registry-side image replacement.
This keeps the human-readable version tag while ensuring builds resolve to the expected image:
FROM ghcr.io/hadolint/hadolint:v2.14.0-debian@sha256:158cd0184dcaa18bd8ec20b61f4c1cabdf8b32a592d062f57bdcb8e4c1d312e2Change
