GitHub Actions is the weakest link | Hacker News

Hacker News commenters argued GitHub Actions should be pinned to commit SHAs, not mutable tags, for safer CI/CD.

The discussion noted that even with SHA pinning, risk can remain through transitive composite actions and NPM dependencies.

The thread also compared tools and alternatives such as Renovator, Dagger, Jenkins, and Travis CI for more controlled workflows.

Main takeaway: immutable references help prevent silent malicious updates from slipping into build and deployment pipelines.
