apps/server/src/http/github-oauth.ts,loginError():new URL("/login")throwsTypeError: Invalid URLin Bun server-side code — a relative path with no base is invalid per the WHATWG URL spec and Bun is WHATWG-compliant. Every error-redirect path in the callback (state mismatch, exchange failure, profile fetch failure, DB error, session error) will produce an unhandled exception and a 500 instead of the intended 302 to/login?error=<code>. Fix:return Response.redirect(\/login?error=${encodeURIComponent(code)}`, 302);` — no URL object needed.security —
apps/server/src/http/github-oauth.ts,handleGitHubOAuthCallbackSet-Cookie: theclaude-hooks-sessioncookie is issued without theSecureflag. SincepublicBaseUrlmust begin withhttps://in production (the config comment and schema comment both enforce this), the browser will still send the cookie over any plain HTTP sub-request, making the session stealable by a passive observer. Add; Securewhencfg.publicBaseUrl?.startsWith("https://"), or unconditionally in practice since local-dev HTTP doesn't require the flag to function (browsers ignoreSecureonlocalhost).9a40b2f696189610c32b- Replace `new URL("/login")` (throws WHATWG TypeError server-side) with `Response.redirect(\`/login?error=${encodeURIComponent(code)}\`, 302)` - Set `Secure` on the session cookie when publicBaseUrl starts with https:// Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>Both findings fixed in the latest push:
