fix(security): realtime dropped the org header and put the API key in the URL - #23
fix(security): realtime dropped the org header and put the API key in the URL#23yakimoto wants to merge 5 commits into
Conversation
… the URL Two defects in `wave/realtime.py`, both flagged against sdk-python. 1. Multi-tenant isolation bypass. `WaveClient._build_headers()` stamps `X-Organization-Id` when `organization_id` is configured, and every other SDK module goes through it. `RealtimeAPI` took only `client.api_key` and built its own header dict that omitted the org, so `publish()`, `presence()`, `history()` and the WebSocket upgrade all ran unscoped — the one surface where a channel subscription is exactly the thing that should be tenant-bounded. 2. API key in the WebSocket URL query string. The inline comment justified it as "Browser/SDK clients can't set headers on the WS upgrade". True of browsers; not true here. This is a Python client using websocket-client, whose `create_connection(url, header=[...])` sets arbitrary upgrade headers. The justification was imported from a constraint that does not bind this code path, and a credential in a URL is recorded by every hop that logs a request line. The key now travels as `Authorization: Bearer` on the upgrade. `token_in_query=True` re-enables the legacy parameter for a deployment that cannot read the header — off by default, documented as insecure, and it does not disable the header when on. 3. Found while reading: `channel` and `as_` were interpolated raw into the query string, and `channel` raw into the REST path. A channel containing `&` injected a query parameter; one containing `/` left its path segment. Now urlencoded (`urlencode`, and `quote(safe=":")` for the path, keeping WAVE's `stream:abc` shape literal). Verified: 9 new tests in tests/test_realtime_auth.py, all passing — org header present on REST and on the upgrade header list, api_key absent from the connect URL by default, legacy param opt-in, and a channel named `stream:abc&as=victim` cannot inject `as`. Full suite: 17 passed, 2 failed, 1 skipped. Both failures are pre-existing on origin/main and unrelated — test_sdk_exports asserts 33 APIs (there are 36) and version 2.0.0 (it is 2.1.0). Proved by running that file against a clean `git archive` of origin/main: same 2 failures, same reasons. Not established: `/v1/connect` does not appear anywhere in wave-realtime-edge@main, so I could not confirm server-side acceptance of the header form from code. `src/landing.ts` documents the edge's auth as `Authorization: Bearer <key>`, which is why header-first is the default rather than a guess — but a live handshake against realtime.wave.online has not been run. Filing that separately.

🟡 Release notes not updated for a user-facing behaviour change
The change alters how credentials and tenant scoping are sent for realtime connections and adds a new opt-in setting (token_in_query at wave/realtime.py:142) without adding an entry to the Unreleased section of CHANGELOG.md, so users get no notice of the behaviour change.
Impact: Users upgrading the SDK will not see that realtime authentication changed or that a new opt-in option exists.
Repository rule requiring changelog updates
AGENTS.md states: "Conventional Commit titles; update CHANGELOG.md (Unreleased) for user-facing changes." The Unreleased section in CHANGELOG.md:7 is empty and untouched by this PR, while the PR changes realtime auth transport (header instead of query token), adds X-Organization-Id to realtime REST/WS traffic, and percent-encodes channel path segments — all user-visible.
Prompt for agents
AGENTS.md requires updating CHANGELOG.md's Unreleased section for user-facing changes. This PR changes realtime authentication (API key now sent in the Authorization header on the WS upgrade instead of the URL query), adds X-Organization-Id propagation to realtime REST and WS traffic, adds a new token_in_query opt-in on RealtimeAPI, and percent-encodes channel names in REST paths. Add appropriate Fixed/Added/Changed entries under ## [Unreleased] in CHANGELOG.md.

🔍 Server must accept the Authorization upgrade header for realtime
Moving the credential out of the URL relies on the realtime gateway accepting Authorization: Bearer ... on the WebSocket upgrade. If the deployed gateway only reads ?access_token=, every existing user's connect() will start failing after upgrade unless they explicitly pass token_in_query=True. Worth confirming server-side support (or gating the change behind a version) before release.

🔍 Channel encoding in REST paths changes the wire format the server sees
_channel_path percent-encodes everything except : (wave/realtime.py:38-44), so channels containing characters like /, #, or spaces now reach the server as %2F/%23 path segments where they previously produced multiple path segments or truncated URLs. Worth confirming the realtime service decodes the path segment before matching channel names, otherwise previously-working channels with unusual characters would start resolving differently.

websocket-client v1.0.0 _handshake.py redirect custom headers create_connection
💡 Result:
In the websocket-client library (including v1.0.0 and later versions), the connection process, including handling redirects and custom headers, is managed within the websocket._core module, specifically through the connect method [1][2][3]. When you use create_connection or WebSocket.connect, you can pass a header argument (as a dictionary or list) to include custom HTTP headers in the initial handshake request [4][5]. Regarding redirects: 1. The library handles redirects automatically during the handshake process [1][2][3]. 2. The core logic iterates through a redirect limit (defaulting to 3, configurable via the redirect_limit option) [1][2][3]. 3. If the server returns a supported redirect status code, the library closes the current socket, connects to the new URL provided in the location header, and performs a new handshake [1][2][3]. Important Note on Custom Headers and Redirects: In many versions of the library, the custom options (including the header dictionary/list) passed to the initial connect call are passed into the handshake function for each subsequent connection attempt during a redirect [1][2][3]. However, developers should be aware that custom headers intended for the original target might be sent to the redirected target as well, as they are persisted in the options object throughout the redirect loop [1][2][3]. If you encounter issues where specific headers should not be sent to the redirected host, you may need to implement manual redirect handling by setting redirect_limit=0 and performing the connection logic manually in your application code [1][2][3].

Authorization: Beareron the upgrade.token_in_query=Truere-enables the legacy parameter for a deployment that cannot read the header — off by default, and it does not disable the header when switched on.3 — Query-parameter and path injection (found while reading)
channelandas_were interpolated raw. A channel namedstream:abc&as=victiminjected anasparameter on the upgrade; one containing/escaped its REST path segment. Nowurlencodefor the query andquote(safe=":")for the path, keeping WAVE'sstream:abcshape literal.Verification
The 9 new tests assert the org header on REST and in the upgrade header list, that
api_keyis absent from the connect URL by default, that the legacy param is opt-in, and thatstream:abc&as=victimcannot injectas.Both suite failures are pre-existing and unrelated.
test_sdk_exportsasserts 33 APIs (there are 36) and version2.0.0(it is2.1.0). Proved rather than assumed — running that file against a cleangit archiveoforigin/maingives the same two failures:Those two stale assertions are worth a separate fix; they are not this PR's to smuggle.
What is NOT established
/v1/connectdoes not appear anywhere inwave-realtime-edge@main, so I could not confirm server-side acceptance of the header form from code I can read.src/landing.tsdocuments that edge's auth asAuthorization: Bearer <key>("this edge makes zero auth decisions"), which is why header-first is the default rather than a coin flip — but no live handshake againstrealtime.wave.onlinehas been run. If the gateway turns out to read onlyaccess_token, the escape hatch isRealtimeAPI(client, token_in_query=True)and the correct follow-up is to fix the server, not to re-widen the SDK.Note
High Risk
Changes authentication transport and tenant headers on realtime REST and WebSocket paths; misconfigured gateways could break connects until
token_in_query=True, while correct behavior fixes credential leakage and org bypass.Overview
Fixes realtime auth and tenant scoping so the Python client matches the rest of the SDK and stops leaking credentials in URLs.
RealtimeAPInow readsorganization_idfromWaveClientand addsX-Organization-Idon REST (publish,presence,history) and on the WebSocket upgrade. Previously realtime built its own headers and only sentAuthorization, so multi-tenant calls could run unscoped.WebSocket connect no longer puts the API key in
?access_token=by default. Credentials go inAuthorization: Beareron the upgrade viawebsocket-client’sheaderargument.token_in_query=TrueonRealtimeAPIrestores the legacy query param for gateways that need it; the header is still sent when that flag is on.Channel safety: connect query params use
urlencode, and REST paths use_channel_path(quotewith:safe) so malicious channel oras_values cannot inject query parameters or break path segments.Adds

Summary by cubic
Secures realtime by scoping REST calls and the WebSocket upgrade to the organization, moving the API key out of the connect URL into the
Authorizationheader, and encoding channel/as_values to block injection. The changes live in thewave_sdkpackage.Bug Fixes
X-Organization-Id, so channels follow the same tenant scoping as the rest of the SDK.Authorization: Beareron the upgrade by default;token_in_query=Truerestores the legacy?access_token=param for gateways that need it, without disabling the header.channelandas_are percent-encoded in query strings and REST paths, so values can't inject parameters or escape the path segment.Migration
access_tokenin the URL needRealtimeAPI(client, token_in_query=True)until the server supports headers.Verified by the new
tests/test_realtime_auth.py; the full 67-test suite passes.Written for commit a73e522. Summary will update on new commits.
Note
Fix realtime authentication to send API key in Authorization header instead of URL
RealtimeChannelnow sends the API key as aBearertoken in theAuthorizationheader and includesX-Organization-Idon WebSocket upgrades; the API key is no longer placed in the connect URL by default.token_in_queryflag onRealtimeAPIandRealtimeChannelrestores the legacy behavior of appendingaccess_tokento the query string for clients that require it.publish,presence,history) and WebSocket URLs now use percent-encoded channel names via the new_channel_pathhelper, preventing path/query injection.token_in_query=True.Macroscope summarized 2f91999.
