A Terraform module registry is a small HTTP protocol: service discovery, a versions list and a download endpoint. What each does and what to ask of yours.
Release notes with security changes called out, artifacts, checksums, signatures, an SBOM and verification steps. Each answers a careful user question.
You cannot upgrade what you did not declare. Four ways to handle a vulnerable transitive dependency: update the parent, audit fix, override, or accept.
When a library has a vulnerability but no fix, apply any vendor workaround, test it, limit reachable calls, track the exception, and plan a replacement.
