CRITICAL: importSubjectContext never validated selfApp, and verifyJwt skips the audience check entirely when audience is undefined. So an undefined selfApp disabled the only cross-app binding in the system and accepted every token from every app for every audience. Not hypothetical - the natural feed is helpers' currentAppName(), which returns string | undefined. The mint side already hard-fails on a missing app name; the import side did not. A non-string tenant id was silently dropped at both ends. A numeric tenant id is the common DB-backed case, and a callee reading a missing tenantId as "global" is a cross-tenant exposure. Now refused, symmetric with the subject check. Token lifetime was unbounded: verifyJwt only checks exp when present, so a token minted without one never expired, and a caller passing a large ttlSeconds produced a long-lived impersonation credential the callee honoured. exp is now required and age is bounded by maxAge independently. targetApp was unvalidated, so passing an array minted one token valid at several apps - exactly what the audience binding exists to prevent. Also documents callerApp as self-asserted rather than authenticated provenance, since the signing secret is workspace-wide. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
WRNexusJS
WRNexusJS is a compiler-driven, SSR-first, Bun-native full-stack framework for building secure, fast, maintainable applications with .wrn pages, layouts, components, stores, server functions, client functions, typed outputs, APIs, validation, authentication, realtime rooms, and production tooling.
Current framework version: 0.8.0
Core principles
- Secure by default with CSP, CSRF, safe serialization, URL policies, request limits, SSRF protection, secret scanning, and release gates.
- Performance-first SSR with zero framework JavaScript for static pages and selective hydration for interactive pages.
- One compiler-understood
.wrnmodel for markup, props, state, outputs, and runtime-specific functions. - Backward-compatible package upgrades with migrations, generated references, validation scripts, and private publishing controls.
- Package kits that give developers public helpers, package tests, documentation, and complete UI blocks where a package has a developer-facing interface.
Quick start
bun install
bun run validate:0.8
bun run check
bun run dev
Create or upgrade a project:
bunx @wrnexus/cli@0.8.0 create my-app
bunx @wrnexus/cli@0.8.0 update --version=0.8.0 --report
Package kits in 0.8
All 39 framework packages expose a documented helper/API surface and package tests. UI-facing packages additionally own complete .wrn blocks composed from @wrnexus/ui:
@wrnexus/auth— complete account, sign-in, sign-up, MFA, passkey, recovery, device, provider, and security blocks.@wrnexus/captcha— challenge, field, status, extraction, verification, response, and context helpers.@wrnexus/i18n— recursive locale loading, fallback chains, request resolution, SSR/browser translations, language controls, and formatters.@wrnexus/image— responsive picture plans, secure loaders, placeholders, preload hints, audits, and image blocks.@wrnexus/realtime— typed messages, room connections, presence, typing, metadata, composer, status, and message blocks.@wrnexus/uploader— upload attributes, result validation, formatting, dropzone, and status blocks.@wrnexus/validation— parse/throw helpers, consistent error responses, summaries, and field errors.@wrnexus/ui— the complete shared design-system component catalog.
Infrastructure packages remain helper/API-only so database, encryption, security, compiler, server, and build packages do not pull browser UI into production server code.
Security note for encrypted HTTP bodies
@wrnexus/encryption supports authenticated application-layer request and response envelopes with method, path, request-ID, timestamp, expiry, key-rotation, body-size, and replay binding.
This feature does not replace HTTPS. It is appropriate for service-to-service calls, native/mobile clients, controlled agents, or selected fields with server-managed keys. It cannot hide data from an end user when a browser receives the decryption key.
