AntiPattern

Auth/State Confusion Leakage

auth-state-conflation

Credential or session state gets conflated across storage and presentation layers, so clients mistakenly assume encrypted strings are “safe by design,” leading to replay/sniffing risks (or outright impersonation) when traffic or tokens can be intercepted and resent.

MATCHESSolution

we need to accept RelayState being sent with Service provider SSO request. — keycloak verifies my saml response and if I have mappers created. Tension: I was ignoring this. Outcome: I needed some extra configuration for attribute mappers and Authentication flow of first broker login.

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

the API keys are stored in an encrypted form — more-annoying techniques (e.g., native code via the NDK). Tension: This too makes it more difficult for an attacker to get the keys. Outcome: but it does not prevent it completely.

MATCHESSolution

do I need to store this URL somewhere safe (i. e. a Key Vault) — or is it public and can be safely stored in the git repository? Tension: Bearer tokens are secrets. Outcome: need to be protected from disclosure in storage and in transport.

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

if you're concerned about the password persisting somewhere either on disk or after your program terminates. Tension: password persisting somewhere either on disk or after your program terminates. Outcome: Lock the memory backing the string such that it c.

MATCHESSolution

Encrypting the plain text locally and storing the ciphertext remotely is the way to go. — You want to have protection from the remote attackers? Tension: Encryption has never solved any problems for us. It has just shifted the problems somewhere else. Outcome: protection from remote attackers is doable.

MATCHESSolution

Store the login token in the client and send it in the Authorization header for future requests

MATCHESSolution

Perform the authorization-code-to-token exchange in the backend to keep tokens and the client secret off the client. Create/establish an app-specific user session (e.g., HTTP session cookies or tokens) and do not use the external provider access token directly for your backend authorization; generate/validate authorization specific to your APIs.

MATCHESSolution

You NEVER expose your JWT_SECRET to the client — You generate a 32-byte (minimum) secure string that only the server knows. Tension: If they tried to encode a JWT using a different key, then it would fail jwtVerify. Outcome: a user cannot forge a token because they don't know the key.

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

I would simply hold the secrets in memory — Based on the logic here. Tension: reading secrets every time disrupts availability. Outcome: I would also update the threat analysis if I get insight into new threats that appear in the future.

MATCHESSolution

Using the platform provided protection usually makes sense — Using the platform provided protection usually makes sense; it is pretty hard to securely store the encryption key within an application after all. Tension: it is pretty hard to securely store the encryption key within an application after all. Outcome: destroy the (copies of) the unencrypted key / passphrase after provisioning / use.

MATCHESSolution

Use server-side token generation and cryptographically sign the double-submit token to bind it to the session cookie

MATCHESSolution

Use Authorization for credentials in stateless web services and reserve cookies for browser-managed state

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

Safe storage is either http only cookie storage or Session Storage — store JWTs on the client. Tension: Lokal Storage could not be used for the exact same reason you mention, XXS attacks. Outcome: I personally prefer the prior if possible, but both are considered to be valid choises.

MATCHESSolution

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

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

If you want to keep a key secret safe — wallet secrets. Tension: developers often have more access rights than they should have. Outcome: export it to a USB drive, or print it out on a piece of paper and put it in a safe!

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

Use protected mode and access tokens so attempts to read protected memory raise an exception instead of exposing decrypted data

MATCHESSolution

Encrypting the refresh token is a good idea — without the need for a database. Tension: If you know that this will not happen to your users. Outcome: that approach might be ok.

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

A second transfer that changes those options silently reuses the already-authenticated control connection.

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.
