Work History

April 2026

1 Commits • 1 Features

Apr 1, 2026

April 2026: ndc-hub security hardening and governance improvements. Implemented restriction: registry-updates.yaml workflow now runs only for trusted sources and non-fork pull requests, preventing potential arbitrary code execution and secret leakage from forked PRs. This change closes a long-standing risk vector in the PR workflow (pull_request_target). The commit e0de71b2154dc5ce120a3ef214d9e95cb088359d documents the rationale and implementation details. Impact: reduced CI/CD attack surface, strengthened repository governance, and preserved integrity of external connectors. Business value: safer code contributions, lower risk of secrets exposure, and more reliable automation.
