Phase 7: Supply-Chain & Security Hardening - #18
Merged
Conversation
CSP directives: - default-src 'none' (deny by default) - script-src 'self' (Trunk-generated JS only) - style-src 'self' 'unsafe-inline' (Leptos needs inline styles) - img-src 'self', font-src 'self', connect-src 'self' - worker-src 'self' (service worker) - manifest-src 'self' (PWA manifest) No unsafe-eval. No external resources.
New CI job 'csp-verify' that: - Extracts CSP value from vercel.json - Validates all required directives are present - Rejects unsafe-eval - Rejects unsafe-inline in script-src - Allows unsafe-inline in style-src (Leptos requirement) - build job now depends on csp-verify
