Trusting Weak Request Signals

weak-request-trust-boundary

Authentication and integrity checks are limited to weak request signals (e.g., IP allowlists, HMAC-only assumptions, or missing tokens/CSRF), so attackers can spoof, replay, or bypass by sending crafted requests that validate superficially but not the real actor.

MATCHESSolution

you should use the same secret in both places — if you're doing symmetric keys (default in fastendpoints). Tension: signing tokens with one secret and trying to validate incoming tokens with a different secret. Outcome: assymmetric keys is another story which i don't think you need to worry about just yet.

MATCHESSolution

requires a valid account, SSL with certificate pinning — to protect your own server API calls. Outcome: This increases the difficulty for an attacker to get the keys.

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

Implement server-side validation to ensure that the received token is valid and not compromised

MATCHESSolution

Use Laravel Sanctum personal access tokens and CSRF tokens to authenticate API requests

MATCHESSolution

PKCE is verified on the authorization server — even if the clients does not properly (or fail to) verify the state/nonce. Tension: PKCE will still protect them. Outcome: PKCE will still protect them.

MATCHESSolution

Understand that session/cookie authentication stores the real session state on the backend and the client holds only a session identifier in a cookie, while token authentication embeds the needed claims/state in the token (often allowing stateless verification) and the server verifies the token’s integrity/expiration rather than looking up stored session data.

MATCHESSolution

First thing's first: HTTPS. — if JWT is a POST parameter or a bearer token under HTTPS. Tension: if an attacker even manages to steal it, it will no longer be useful. Outcome: you could make it a one-timed token.

MATCHESSolution

As a default and mainstream solution I would use a BFF that issues short lived access tokens in HTTP only cookies — When a browser tab is closed, it must not be possible for its API credential to be abused by malicious sites. Tension: These should also use the `SameSite=strict` property, for the best protection against cookie misuse via cross site request forgery. Outcome: These should also use the `SameSite=strict` property.

MATCHESSolution

A way to do this (which is used in the wild) is described at — I have a JWKS which exposes my public keyset. Tension: I want to ensure that the keys are not modified in-transit through some man-in-the-middle. Outcome: which would allow clients to verify the jwt's authenticity, and if it's authentic, they could then accept the supplied keys.

MATCHESSolution

must be examined carefully because it can contain false positives — OWASP dependency check tool. Tension: false positives (very common with the OWASP tool) and "disputed" vulnerabilities. Outcome: must be examined carefully.

MATCHESSolution

Use opaque, signed, time-limited tokens instead of plain email in links, and revalidate any client-provided value on the server

MATCHESSolution

Add request throttling/rate limiting (e.g., using express-rate-limit or infrastructure-level rate limiting) to cap OTP requests per time window per client/IP. Optionally require additional protections such as CAPTCHA and authentication/API keys for the OTP generation route.

MATCHESSolution

PKCE protects against a specific vulnerability. — if something can intercept the redirect. Tension: the `code` alone is useless because they need the `code_verifier`. Outcome: they need the `code_verifier` which lives in the app that originally initiated the `authorization_code` flow.

MATCHESSolution

"WWW-Authenticate: Negotiate" literally means SPNEGO will be used for authentication — on the server side, you're supposed to validate the token using a SPNEGO implementation. Tension: If the client starts by sending an NTLM token instead of Kerberos, that is not because of a missing header. Outcome: you haven't registered a SPN for the server within Active Directory.

MATCHESSolution

Your hardware token idea is the only thing you've listed that is plausible — assuming the token's hardware has its own clock and is hardened against tampering. Tension: There is no way to trust hardware that someone else controls. Outcome: This is just a computer that you trust because the user does not control it.

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

Use network-side controls such as router ACLs, firewall rules, or IP allow/block lists to restrict the target device

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

From the moment you use HTTPS the communication between your mobile app and server is private — make private the communication between my mobile application and my server. Tension: someone can intercepts http calls and copy the static token. Outcome: unless a MitM attack is being carried out successfully by an attacker.

MATCHESSolution

check out this link for self-checking — If you were using a Linux server and had any suspicions. Tension: determine whether any compromises had taken place.

MATCHESSolution

Regularly checking your codebase against common vulnerabilities — by utilizing OWASP, CWE, etc. Tension: security score might not be sufficient for tomorrow.

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

You can limit TLS sniffing using certificate pinning. — for some situations, it's worth the trouble. Tension: Google does not recommend this because it's hard to manage. Outcome: See also HTTP Toolkit's discussion on the topic.

MATCHESSolution

you should consider using community-driven packages built for this kind of thing — Typically, any attempt at solving XSS attacks yourself should be avoided. Tension: they will find these pseudo-protocol calls. Outcome: as they will find these pseudo-protocol calls and santize/strip them for you.

MATCHESSolution

implement something like Attestations Service — based on App/Device integrity or reputation verification.

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

Use HTTPS/TLS for the site (and verify with a packet capture tool like Wireshark/tcpdump that traffic is encrypted). Treat DevTools payload viewing as client-side request contents rather than evidence that encryption is missing.

MATCHESSolution

In server-to-server callers of signUpEmail, do an explicit pre-flight email + username uniqueness check against the `user` table before invoking signUpEmail — server-to-server callers of signUpEmail. Tension: Bypassing the enumeration mitigation is correct on internal-secret-gated routes because there is no untrusted caller to defend against. Outcome: return a clean 409 on collision. Add a belt-and-braces post-call check: SELECT user.id WHERE id = result.user.id — if the row doesn't exist, refuse to use the id.

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.
