feat(auth): API authentication – MVP by snabo1988 · Pull Request #24 · unified-error-codes/csds

snabo1988 · 2026-01-30T23:26:00Z

Summary

Introduces MVP-level API authentication for CSDS.

This PR adds a simple token-based authentication layer to secure API endpoints
required for MVP scope.

Scope

HTTP Bearer token authentication
Authorization dependency for protected endpoints
Minimal scope validation (sessions:read)
Aligned with MVP requirements (no user management yet)

Out of scope

User accounts
Token rotation
Role-based access control (RBAC)

Notes

Authentication was implemented before automated tests as a prerequisite
for validating protected API endpoints.

The PR title says this is Authentication but this is rather Authorization

csds/uec_csds/api/sessions.py


 router = APIRouter()

+@router.get("/sessions", dependencies=[Depends(require_scopes({"sessions:read"}))])


Why second session endpoint? How it works with the other conflicting one ?

Good catch — this was an intermediate MVP artifact.

There is no intention to expose two /sessions endpoints. The duplicate route was introduced while testing scope-based authorization and was not meant to coexist long-term.

The implementation has now been consolidated into a single /sessions endpoint, which:

enforces sessions:read authorization

returns faulted sessions via the defined response model

removes any routing conflict or ambiguity

Authentication is handled earlier in the pipeline; this endpoint only performs authorization and data access.

Thanks for flagging this — resolved in the latest commit.

Please do not modify unrelated code nor introduce the unrelevant changes to the task. If you you like to introduce not related changes please do this in dedicated PR or at least in dedicated commit.

You’re right — the logging-related changes are not directly related to the scope of this PR.
I have reverted those changes and limited this PR strictly to the authentication/authorization-related logic and required wiring.

Any logging or other cross-cutting improvements will be proposed separately in a dedicated PR (or at least a dedicated commit), to keep the scope clean and reviewable.

Same. Why to touch this file?

You're right — this change is unrelated. I will revert the .gitignore
modification to keep the PR focused.

How we assure that given scopes comes from trusted source?

Scopes are not taken from the client. They are assigned server-side based
on trusted configuration for a given API key. This is a deliberate MVP
trade-off.

This is not true. Please remove this ADR files. I haven't seen practice to push such files into the repo. No one will ever read this files, hence I think there is no reason to add them. Better place for such description would be the GH test/issue itself rather the code/repo.

What is the purpose of this change ? db and app are already created in csds.py.

@snabo1988 I think more important would be to focus on #23. Currently verifying changes is very cumbersome.
