JWT Misuse With Static Tokens

jwt-static-token-misvalidation

Bearer JWTs get misconstructed or misvalidated (wrong middleware responsibility, shared session state, or embedded static secrets), so tokens can be accepted when they shouldn’t be or replayed elsewhere, enabling cross-app request forgery and endpoint enumeration after password changes.

MATCHESSolution

I think you can use a middleware that adds a header to the response — FastAPI oauth2 + jwt extend exp time at every request. Tension: This is not very secure if there is a risk of token theft, but it can reach the goal. Outcome: response.headers["bearer-refreshed"] = access_token.

MATCHESSolution

configure the session option with the maxAge property to define the token's lifespan — In your auth.ts file. Outcome: add logic to the jwt callback.

MATCHESSolution

Enable JWT-based sessions (`session.strategy = 'jwt'`) and add `callbacks.jwt` to save `account.access_token` onto the JWT, plus `callbacks.session` to copy that value into `session.accessToken`. Update TypeScript types (e.g., `types/next-auth.d`) so `session.accessToken` is available.

MATCHESSolution

Add headers: { Authorization: `Bearer ${token}` } to the mutation query

MATCHESSolution

the information about the user is inside the JWT — other services does not need to call the authorization service or database. Tension: this token is signed from the authorization service but other services does not need to call the authorization service or database. Outcome: they only need a shared secret they use to check the validity of the token.

MATCHESSolution

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

MATCHESSolution

Make sure your transaction token cannot be resuable

MATCHESSolution

Setting the expiration of the JWT token for me only works when I add it during JWT-callback — Regenerating a new JWT token can be achieved with setting `refetchInterval` of `SessionProvider`. Outcome: token.exp = Math.round(Date.now() / 1000) + JWT_TOKEN_EXPIRES_IN_SECONDS.

MATCHESSolution

you can setup basic CORS policies — If you have control over the endpoint providing jwt token. Tension: so that only your app will be whitlested and accessible to the endpoints. Outcome: Here is the sample example for CORS settings.

MATCHESSolution

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

on subsequent requests. Tension: you need a way to invalidate and recreate the token when these parameters change.

MATCHESSolution

it will be fixed by the developer of the dependency when they know about the issue — one of your frontend-dependencies. Tension: for now the attacker can read/export the JWT of your user. Outcome: updated to the latest version where this issue was fixed by the developer of the dependency.

MATCHESSolution

send token in headers — Then try using protected endpoint. Tension: Swagger will not store your token and attach it to every request.

MATCHESSolution

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

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

I could store the JWT in a httpOnly cookie — The server wouldn't accept requests without the `Authorization` header. Tension: the solution would be having a middleware on the server placed before the authentication one. Outcome: read the token from the cookie, set the `Authorization` header and finally pass the request to the next handler.

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

the JWT token should be evaluated in the resource server — whatever system that relies on a JWT token validates it properly. Tension: the signature and relevant claims like the `aud` claim etc. Outcome: the JWT token should be evaluated in the resource server.

MATCHESSolution

Access token generated by a user, also typically includes the AMR claim and access tokens using client credentials flow do not contain the AMR claim. — with IdentityServer, you have a concept of ClientClaims. Tension: ClientClaims are claims that are specific to a client and not vary depending on the user. Outcome: One option is to include a client claim, that is specific to the client that requested the tokens.

MATCHESSolution

I guess I'm looking for a kind a JWT associated to the ID without expiration but maybe there is better solution. — Generate unpredictable/unforgeable URL from predictable ID. Outcome: I think your idea of using a JWT makes the most sense.

MATCHESSolution

generate new token every time when workspace is changed — adding/removing to workspace as a business logic. Tension: business logic that invalidates token. Outcome: you can treat adding/removing to workspace as a business logic that invalidates token.

MATCHESSolution

Store both token types in the OAuth2AuthorizationService so revoke/introspect can work for access tokens as well as refresh tokens; if you want to avoid per-request introspection, configure clients to trust JWTs without calling introspection unless they need to confirm revocation.

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

I'm verifying the user OTP to change password — after change password. Tension: unable to create access and refresh token using JWT.
