Redirect Miswiring Risks

broken-redirect-flow

Redirect-related plumbing fails when code builds the wrong URL or improperly handles redirect flow, causing client-controlled or malformed redirects (including loops) to trigger incorrect outcomes or failures instead of reliable payment/session navigation.

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

It should be fixed as of version 13.2.3 and above — If you're wondering what was causing this issue. Tension: If you really have to use a version that has this issue. Outcome: you can use Joseph Schmoe's solution with `redirect`.

MATCHESSolution

to your GoRouter. Outcome: You could also try to use the redirect function.

MATCHESSolution

try separating your sign-in and sign-up pages — In addition to defining the path in env. Tension: This seems to have solved the redirects for me. Outcome: update the sign-in, sign-up paths in the dashboard.

MATCHESSolution

Clear the cookies and test it — on another browser. Tension: private routes all redirect to the home page. Outcome: it went trough just fine.

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

I added the below redirect URL to the Web Platform in the Api App registration. Tension: AADSTS9002325: Proof Key for Code Exchange is required for cross-origin authorization code redemption. Outcome: http://localhost:8000/docs.

MATCHESSolution

You can use the `redirect` option to keep the customer on the page when confirming the checkout — when confirming the checkout. Tension: This only works for payments that can happen entirely on your page. Outcome: const result = await checkout.confirm({ redirect: 'if_required' });.

MATCHESSolution

I'm using Stripe in my NextJS 14 application. Tension: I don't want to run this code from the thank you page I'm currently redirecting from. Outcome: I'm expecting to run some code after successful payment and only then redirect to return_url.

MATCHESSolution

Checkout Session is designed to redirect users only when a payment is successful. — with Checkout Session. Tension: when a payment fails, the users stays on the same page to allow them to retry the payment. Outcome: This way, when a payment fails, the users stays on the same page to allow them to retry the payment.

MATCHESSolution

fetch(url, { method: 'POST', redirect: 'follow'}) — frontend app is configured to follow the server-side redirect. Tension: not being automatically redirected. Outcome: fetch(url, { method: 'POST', redirect: 'follow'}).

MATCHESSolution

-browser back button = the customer should get redirected back to your endpoint — To loop back to your issue:. Tension: you could implement it to handle a second visit after Session creation differently.

MATCHESSolution

There's no simple solution to this. — when redirection is required. Tension: this doesn't really solve the issue when redirection is required. Outcome: I would try using the redirect `if_required` option.

MATCHESSolution

not redirect if the URL is already `/admin/main/users` — if ( adminconfig?.matcher.includes(pathname) || pathname.startsWith("/admin/") ) {.

MATCHESSolution

Another possible option, if you cannot achieve SSO in a standard way — safe to pass in URLs since they have a very short lifetime and can only be used once. Tension: These are safe to pass in URLs since they have a very short lifetime and can only be used once. Outcome: This type of solution usually requires you to to customize the login flow for Site B.

MATCHESSolution

Option 2 is often preferred within the same domain — making AJAX calls. Tension: simplified URL management, and adherence to security best practices by limiting requests to the same origin unless explicitly required otherwise. Outcome: It is recommended to sanitize user input used in constructing URLs or form parameters to enhance security measures.

MATCHESSolution

HttpClient.GetAsync(new Uri(TextHelper.RedirectUrlNull(urlContent))); — We have an issue in our solution (we are using .net core). Tension: the SNYK vulnerabilities scaner show us that we have a Server-Side Request Forgery (SSRF) vulnerability.

MATCHESSolution

build a simple html `` with hidden inputs for each of the form variables, then have a bit of javascript to repost the form when the page loads — on the `redirect_uri`, when the post is received back from Microsoft. Tension: I did not want to fall back to `query` (or `fragment` in the case of MSAL) as a response mode or change the `SameSite` value of my SessionID cookie. Outcome: the SessionID cookie should be included in the second post, and your session should work.

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

Use the documented `return_url` pattern where Stripe appends `payment_intent` and `payment_intent_client_secret` to the redirect URL; ensure the redirect page is served over TLS/HTTPS and do not log or expose the secret beyond the customer.

MATCHESSolution

Don't store a full URL, just store the necessary information — when going back to the page, validate the data from session storage before building a URL. Tension: not (for instance) a full URL. Outcome: validate the URL before using it.

MATCHESSolution

Resolve the conflict by handling redirection consistently in Cloudflare (and/or disabling the Apache redirect for the same purpose), then set Cloudflare SSL/TLS encryption to Full (Strict) so HTTPS upgrades and redirects complete without looping.

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

redirect-uri: "https://localhost:41448/redirect-uri" — Here’s my application.yml configuration:.

MATCHESSolution

Move the `redirect()` call outside the `try/catch` (e.g., set a success flag and redirect after the block), or in the `catch` re-throw only redirect-related errors so they can propagate.

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

Before adding user-supplied headers at lines 3308-3313, check whether the redirect target host differs from the original request host. Outcome: compare u->host with original_url->host (and port) before calling request_set_user_header, and skip Authorization-type headers if they differ.

MATCHESSolution

Add memcmp verification when stripping CWD prefix. Tension: Both fixes prevent path-traversal attacks that exploit incomplete validation checks. Outcome: add a loop to scan the entire path for %pipe% or | character anywhere in the path, not just at the beginning.

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.
