AntiPattern

Header-Based Auth Validation

untrusted-header-identity

User-supplied HTTP request headers drive auth/identity (e.g., IP/heartbeats) but the server cannot verify authenticity, so validation annotations miss gaps (class-level @Validated, empty-string @NotBlank) and misconfigurations return wrong errors.

MATCHESSolution

Implement role-based authorization as a reusable dependency (e.g., a callable class used with Depends) that loads the current user from the token and raises HTTP 403 when the user's role is not in the allowed roles; apply the dependency to routes.

MATCHESSolution

Define `id` as a non-input private attribute (hidden from validation/schema) and generate it server-side using `PrivateAttr` (with `default_factory` for dynamic defaults). Keep `name` as the only public validated input field; the endpoint can still accept the original model type for consistent validation of `name`.

MATCHESSolution

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

MATCHESSolution

Attach an authentication dependency to only the endpoints that must be protected—either by adding `Depends(...)` (e.g., `HTTPBasic` or the configured AuthX dependency) directly on each protected route or by registering those routes under a separate `APIRouter` with the required auth dependency.

MATCHESSolution

adding an tag, where I pass the credentials in the base64-encoded format — openapi-generator-maven-plugin configuration. Tension: This should allow the plugin to authenticate with the server hosting the shared model. Outcome: pass the credentials in the base64-encoded format.

MATCHESSolution

Only allow specific file types (JPG, PNG) and impose size limits (OWASP) — Input Validation and Sanitization. Tension: prevent injection attacks. Outcome: Validate and sanitize all uploaded images.

MATCHESSolution

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

MATCHESSolution

Use Hash-Based Message Authentication Code or any cryptographic library or built-in .NET classes

MATCHESSolution

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

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

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

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

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

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

MATCHESSolution

JWT implementations hash the header.payload bytes with SHA-256 to produce a fixed-length digest, then sign that digest; this keeps signatures smaller and makes signing/verifying efficient while preserving integrity.

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

jwtAuthFilter was triggered. — i sent a request by Post man on "localhost:8085/api/auth/login". Outcome: OncePerRequestFilter has shouldNotFilter method to avoid filtering for some requests.

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 Swagger UI's built-in requestInterceptor to add the Authorization header to Swagger UI requests while excluding the spec-load request (e.g., via a req.loadSpec check).

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

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

MATCHESSolution

create custom validator interface and try to implement it — @RestController. Outcome: @Validated // Important! Required for custom validation to work.

MATCHESSolution

Create a custom method-level annotation (e.g., `@AuthorityRequired`) that itself is meta-annotated with `@PreAuthorize` and uses the annotation attribute via `#root` to pass the required authority dynamically, backed by a custom security expression root/root object that exposes the needed evaluation context.

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 also needed to change my request matcher — if (!swagger && !error) then apply CustomAuthenticationFilter.

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

Use a central WaveConfig plus AuthLevel union — TypeScript benchmark demo. Outcome: Dashboard rendering should consume wave labels/auth metadata instead of inferring cold/warm from agent IDs.

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.
