Amazon Q CVEs, Hijacked npm and Go Packages, AWS WAF HTTP/2 Issues, Lambda MicroVMs, and Why Execution Is the Boundary Now

This week on Ship It Weekly: Amazon Q Developer and the AWS language servers had a pair of trust-boundary CVEs, JFrog found hijacked npm and Go packages using hidden VS Code tasks to run malware when a workspace opens, AWS WAF had HTTP/2 request-body inspection issues, and AWS introduced Lambda MicroVMs for running user-generated and AI-generated code in isolated sandboxes.The bigger theme: execution is the boundary now. The repo, the IDE, the AI assistant, the WAF, and the sandbox all sit at the point where something gets to run, inspect, block, or decide. Before execution, trust is a policy. After execution, trust is a blast radius.In the lightning round, Brian covers GitHub’s record advisory volume, Git 2.55, Valkey 9.1 on Amazon ElastiCache, and a quick Fable 5 callback now that Anthropic’s Fable 5 is back online.LinksAWS security bulletin: Amazon Q / AWS language server CVEs https://aws.amazon.com/security/security-bulletins/2026-047-aws/JFrog: Hijacked npm packages using VS Code tasks https://research.jfrog.com/post/hijacked-npm-vscode-tasks-blockchain/AWS security bulletin: AWS WAF HTTP/2 inspection issues https://aws.amazon.com/security/security-bulletins/2026-048-aws/AWS Lambda MicroVMs https://aws.amazon.com/blogs/aws/run-isolated-sandboxes-with-full-lifecycle-control-aws-lambda-introduces-microvms/GitHub Advisory Database record volume https://github.blog/security/supply-chain-security/inside-the-advisory-database-and-what-happens-when-vulnerability-volume-breaks-records/Git 2.55 highlights https://github.blog/open-source/git/highlights-from-git-2-55/Amazon ElastiCache Valkey 9.1 https://aws.amazon.com/blogs/database/announcing-valkey-9-1-for-amazon-elasticache/Claude Fable 5 and Mythos 5 model docs https://platform.claude.com/docs/en/about-claude/models/introducing-claude-fable-5-and-claude-mythos-5This week’s On Call Brief https://www.tellerstech.com/on-call-brief-news/2026-W27/More episodes and full show notes https://shipitweekly.fm/
