Hacker News Comment Review
The real supply-chain risk is not source code exfil but potential exposure of CI signing keys or release publish credentials, which create a long-tail threat no ticket closes.
Commenters recommend hardening GitHub Actions immediately: run static analysis with zizmor, set pnpm minimum-release-age, and add Socket Free Firewall on CI npm installs.
A subtle GHA injection vector was flagged: PR titles and descriptions containing backtick-wrapped text can trigger unintended command execution in workflow runs.
Notable Comments
@jonnyasmar: “CI signing keys or release publish creds going out the door is supply-chain. That’s a long tail nobody gets to close by filing a ticket.”
@vldszn: Concrete GHA hardening steps: zizmor static analysis, pnpm minimum-release-age 4320, Socket firewall on CI installs.
