Pattern

Redirect and State Trust

untrusted-redirect-state

Client-controlled redirects and environment-dependent routing cause payment and application state to be inferred from untrusted navigation outcomes, so paystate/query parameters or redirect chains mislead systems until retries, platform quirks, or redirect limits break correctness.

I'm building a Next.js 14 app that uses Zustand with the persist middleware to store authentication tokens and user info. Tension: authenticated pages redirect me to /error/unauthorized. Outcome: React has detected a change in the order of Hooks...

Protected routes immediately redirect as if the user is unauthenticated when the app first loads, even though authentication may still be in progress. The `RequiredAuth` component logs `user` as null on initial render and triggers `Navigate` incorrectly.

PrivateRoutes conditionally returns a function/JSX in a way that triggers a React warning about returning a function or performing side effects during render. The component is also trying to log out users based on token expiration.

When a React Query error triggers a redirect to /login, the browser URL updates but the rendered content does not change to the login page until the user manually interacts with the page.

I get exception of Invalid saml response. — I redirect the browser then from XYZ app to Keycloak using the redirect URI i get from Identity provider i configured. Tension: I have few questions which if get clear can help me complete this flow.

requests with the forbidden fields sailed through to the write path. Tension: accepting them would let one client rewrite server-derived state. Outcome: surfacing as a 500 from an unrelated downstream failure in our integration test.

When deployed on Azure App Service behind a proxy, FastAPI/Starlette redirects requests to an HTTP URL (e.g., HTTP Location header in a 307) instead of preserving HTTPS. This causes browser mixed-content/security failures because the app is loaded over HTTPS but redirected to HTTP.

AADSTS9002325: Proof Key for Code Exchange is required for cross-origin authorization code redemption. Tension: redirects uris not matching.

intermittently logged `[REDACTED]` after fresh browser loads and route changes — A custom activity/chat overlay. Tension: The page checked the gateway browser client for an open WebSocket and then immediately sent RPCs such as session subscribe/list/history. Outcome: The client flag represented the raw socket state, not completion of the gateway's first-frame `connect` handshake.

on successful payment, fronend automatically redirects to `return_url` — in `ui_mode:'custom'` ? Tension: I dont want it to redirect and want to handle things myself. Outcome: Is there a way to stop redirection in `ui_mode:'custom'` ?

This is too much information: is there a single definitive statement that the money has been paid — I'm testing a payment link application with the CLI. Tension: isn't in some state where it might not eventually be paid? Outcome: The simplest test is that `checkout.session.completed` has a status of `paid`, but is this sufficient?

Stripe never renders (just a white screen) — WKWebView. Tension: it appears Stripe’s onboarding is blocked in WKWebView. Outcome: SFSafariViewController delegates don’t expose intermediate redirects.

it redirect's the customer to the checkout page — when the customer clicks on subscription for a particular plan on the pricing table. Tension: I want it to redirect it to my appliction payment page instead of the stripe checkout page. Outcome: can this be done in stripe or is there any other way i can proceed?

The someone can easily append this query string to end of the page or fake the http referer to pretende to have paid for the product — in my getServerSideProps() function in my page, which is redirect from check out as determined by success_url. Tension: I need a server side check too. Outcome: How can I do that?

Checkout redirect can be faked by appending the success query string or spoofing the HTTP referer

Stripe sends the success event before redirects to the success url — when the payment completes. Tension: I save the payment intent id with the order id in data base. Outcome: It's rare yes, but not impossible.

the redirect would be blocked by browser after successful payment — if I load the addin in a office web (microsoft 365) excel document in the browser. Tension: it is actually trying to navigate the top level window. Outcome: How can i achieve the behavior that the taskpane addin that is hosted inside should only be redirected?

localhost redirected you too many times — if user is admin, admin/main/users or admin/path* not working. Outcome: not-admin redirecting is working.

After calling the async register thunk, the user needs to be redirected only when registration succeeds; otherwise errors should be shown without navigating.

The Heroku-hosted MERN app receives many automated-looking requests from the same forwarded IP in the same second, with suspicious query/path content (e.g., unexpected “if”/“php” strings). This behavior appears to be scanning or an attack proxy and raises concerns about security and abuse.

Whether it is safe to include a Stripe PaymentIntent client_secret in the redirect/return URL query parameters during payment confirmation.

a single Cypress test cannot span across multiple origins — we are just trying to test that clicking that button redirects to the correct URL. Tension: instead of allowing the redirect and attempting to read the new URL, we tried to stub the redirect, block it and read what the application is trying to. Outcome: Once the stub is in place, I clicked the button to invoke the method.

Accessing https://example.com results in a “too many redirects” loop, while other domain variants redirect correctly for a React app served by Apache with Cloudflare-managed DNS/SSL.

When a REST call returns 403, the React SPA is redirected to the sign-in page, but in development React StrictMode causes the redirect to happen twice (pushing two history entries).

After signing in, middleware redirection occurs, but the browser URL remains unchanged (e.g., it doesn't update to the intended callback/protected route).

even when correct username and password is provided, even in that case the control is redirected to login page instead of home page — I was implementing an authentication mechanism for my app.

I see multiple redirects in the network tab. I have this error: ERR_TOO_MANY_REDIRECTS — I'm working on a REST API using Java 21 with Spring Boot 3.3, and I'm trying to implement authentication through an external site using OpenID.

In Next.js 15 App Router server actions, calling `redirect()` inside a `try/catch` causes `NEXT_REDIRECT` to be thrown and then swallowed by the `catch`, preventing the redirect from happening.

A web app welcome/onboarding page was shown based on a stale auth session field and a browser localStorage fallback. — Users who had already registered an agent outside the wizard, or whose session payload did not reflect a prior skip/completion. Tension: could still be redirected to the welcome page. Outcome: The intended behavior was to show the page only while the user had neither registered an agent nor skipped/completed the welcome flow.

Wget before 1.21.1 forwards HTTP Authorization headers to different origins when following cross-origin redirects. — when following cross-origin redirects. Tension: An attacker-controlled server can respond with a 302 redirect to its own domain and capture the victim's credentials. Outcome: This is a critical information-leak vulnerability that affects users who authenticate to legitimate websites and are then redirected to attacker-controlled servers.
