CodeBreach in AWS CodeBuild, Bazel TLS Certificate Expiry Breaks Builds, Helm Charts Reliability Audit, and New n8n Sandbox Escape RCE

This week on Ship It Weekly, Brian looks at four “glue failures” that can turn into real outages and real security risk.

We start with CodeBreach: AWS disclosed a CodeBuild webhook filter misconfig in a small set of AWS-managed repos. The takeaway is simple: CI trigger logic is part of your security boundary now.

Next is the Bazel TLS cert expiry incident. Cert failures are a binary cliff, and “auto renew” is only one link in the chain.

Third is Helm chart reliability. Prequel reviewed 105 charts and found a lot of demo-friendly defaults that don’t hold up under real load, rollouts, or node drains.

Fourth is n8n. Two new high-severity flaws disclosed by JFrog. “Authenticated” still matters because workflow authoring is basically code execution, and these tools sit next to your secrets.

Lightning round: Fence, HashiCorp agent-skills, marimo, and a cautionary agent-loop story.
