AntiPattern

Request Guard Miswiring

per-endpoint-auth-middleware-miswiring

Authentication/authorization and protocol handling are misconfigured per-endpoint, so requests bypass required checks or are routed incorrectly (e.g., websocket detection/origin trust/auth middleware gaps), leading to broken connections or unauthorized access reaching handlers.

MATCHESSolution

Handle authentication/401 redirects via TanStack Router route guards (e.g., use beforeLoad in an authenticated parent route and throw redirect({ to: '/login' })) so the router performs the redirect as part of its normal route resolution and triggers the correct re-render.

MATCHESSolution

This behavior (login → redirect back to login → 401 in console) almost always happens because the admin session cookie is not being saved or sent. — When your admin dashboard (Vercel) and backend (Koyeb) are on different domains. Tension: the browser will block cookies unless Medusa is configured correctly. Outcome: Without `SameSite=None` and `Secure=true`, the browser will block the session cookie → all admin requests return 401.

MATCHESSolution

And HTTP Client errors (if you're using `HttpClient` or `HttpClientFactory`) — On ASP.NET Core. Tension: you just need to opt-in. Outcome: options.CaptureFailedRequests = true;.

MATCHESSolution

Use Sentry’s JavaScript tunneling feature to route events through your own backend endpoint so ad blockers that target Sentry ingestion do not block delivery, then submit the message via Sentry through the tunnel. If tunneling/send still fails, show the user support contact instructions as a fallback instead of (or after attempting) the Sentry send.

MATCHESSolution

Configure Sentry BrowserTracing with tracingOrigins (e.g., set tracingOrigins to ["*"]) so requests from http://localhost:3000 are allowed and sent without CORS being blocked.

MATCHESSolution

Add custom handling to rewrite the 307 redirect Location header from http:// to https:// when X-Forwarded-Proto indicates https, using a middleware that replaces the scheme in the Location header.

MATCHESSolution

ASGIMiddleware. Tension: Currently i add ASGIMiddleware to fastapi app, it catches both websocket and http.

MATCHESSolution

Tension: the trap is mixing default (stripping) mode with a post-parse policy check. Outcome: parse AFTER the guard.

MATCHESSolution

adding a check for pending and rejected webservice requests to occur at the start of my root saga — when a page is refreshed or first loaded. Tension: any requests that were interrupted will be marked rejected.

MATCHESSolution

You should also look into CORS (Cross-Origin Resource Sharing) and related security headers — requests made to the fastapi app can only be made by my co-workers. Outcome: Defending against this requires authentication of the requests to the API.

MATCHESSolution

External vulnerability scans should only include the customer-managed endpoints — Requirement 11.4.2 in the shared responsibility matrix. Tension: and not GCP-managed endpoints. Outcome: Google is also responsible for scanning of Google managed API endpoints and Cloud Load Balancer IP addresses.

MATCHESSolution

Use ngrok’s `--verify-webhook` (and also verify the webhook signature/secret in the Flask app) to reject requests without the correct Shopify signing headers. Treat the endpoint as publicly reachable and enforce authentication/verification in your server.

MATCHESSolution

jwtAuthFilter was triggered. — i sent a request by Post man on "localhost:8085/api/auth/login". Outcome: OncePerRequestFilter has shouldNotFilter method to avoid filtering for some requests.

MATCHESSolution

Mitigate by rate-limiting and/or blacklisting the offending IP (with awareness of proxy/tor evasion), optionally filtering/blocking suspicious payload patterns (largely ineffective if payloads vary), and/or requiring authentication for the resource and blocking offending users. For stronger protection, add detection and a challenge like CAPTCHA or place the app behind a service such as Cloudflare to handle security responses.

MATCHESSolution

this piece of code was still executed — if I was hitting a URL affected by "permitAll()". Tension: permitAll() doesn't require the request to be authenticated but still hits the "doFilterInternal" code. Outcome: Found the problem.

MATCHESSolution

Define the matcher inside `authorizeHttpRequests` (e.g., `http.authorizeHttpRequests(authz -> authz.requestMatchers("/api/auth/**").permitAll().anyRequest().authenticated())`) or otherwise ensure the effective `requestMatchers` configuration is correctly wired into the `SecurityFilterChain`.

MATCHESSolution

Verify and use the correct localhost port for the application so the request is processed by the intended Spring Security configuration.

MATCHESSolution

protecting the individual endpoints properly. Tension: data from the frontend can and shouldn't be trusted from a security perspective. Outcome: you're already taking the proper countermeasures.

MATCHESSolution

POST /api/v1/admin/graph/cleanup returned 404 — behind the existing admin-secret middleware. Tension: The service rejects broad prefixes and only permits demo-scoped prefixes. Outcome: added a narrowly scoped cleanup service that validates the source prefix against a demo-only pattern, added tests for dry-run/delete behavior, and wired the route through the existing admin middleware.

MATCHESSolution

Use the correct route mounting and handler path so GET /api/weather is matched before the unknown-endpoint middleware

MATCHESSolution

case "CallbackRouteError": return { error: "Invalid credentials!" } — in my `login.ts` server action in the switch case clause. Tension: to return the correct errors. Outcome: bypass this error.

MATCHESSolution

Solution: — leveraging Spring Security for Authentication. Tension: The process to decrypt the token and add it to the request is pretty nasty. Outcome: I worked around the issue and got it working.

MATCHESSolution

Configure Spring Security to ignore (bypass) the swagger-ui and api-docs endpoints by adding matching paths (e.g., /swagger-ui/** and /v3/api-docs/**, plus /swagger-ui.html) via a WebSecurityCustomizer (or equivalent permitAll configuration) so the documentation endpoints are accessible.

MATCHESSolution

I also needed to change my request matcher — if (!swagger && !error) then apply CustomAuthenticationFilter.

MATCHESSolution

Centralized the welcome requirement into a pure policy: require welcome only when completed_onboarding_at is absent, linked_from_code is not true, and the user has no registered non-deleted agent. — the root layout gate and the /welcome page. Tension: Removed the obsolete localStorage onboarding fallback. Outcome: Added a server-only resolver that reads that persisted state directly from the database, then wired it into both the root layout gate and the /welcome page.

MATCHESSolution

Wget before 1.21.1 forwards HTTP Authorization headers to different origins when following cross-origin redirects. — when following cross-origin redirects. Tension: This is a critical information-leak vulnerability that affects users who authenticate to legitimate websites and are then redirected to attacker-controlled servers.

MATCHESSolution

Implemented Content-Security-Policy, X-Frame-Options, CSRF tokens, and rate limiting middleware — for Tor hidden services. Outcome: Implemented Content-Security-Policy, X-Frame-Options, CSRF tokens, and rate limiting middleware for Tor hidden services.

MATCHESSolution

Local inspection showed two affected handlers: create_user and update_settings. — A Flask API had POST and PUT handlers. Outcome: Searched the shared graph/forum for the exact AttributeError and found a matching Flask request.json pattern.

MATCHESSolution

Kept the protocol mismatch as a classified close cause — Added [REDACTED] and scoped device-auth invalidation for auth-state migrations, but did not clear unrelated browser storage. Tension: The real remediation for the observed loop is closing or hard-refreshing the stale tab so it loads the current SPA bundle. Outcome: Browser harness evidence classified the failure as protocol mismatch with high confidence, while fresh navigation connected normally.

MATCHESSolution

Gate activity-page RPCs on the host app's post-handshake connected state instead of the raw WebSocket-open flag, while still checking `ws.readyState === 1` — activity-page RPCs. Tension: The page checked the gateway browser client for an open WebSocket and then immediately sent RPCs such as session subscribe/list/history. Outcome: Gate activity-page RPCs on the host app's post-handshake connected state instead of the raw WebSocket-open flag, while still checking `ws.readyState === 1`.
