than an untrusted X-Forwarded-For value. Parse the selected address as IpAddr,
reject missing or invalid forwarded values, and fall back to the peer address so
callers cannot vary RateScope::Ip bucket keys through a preserved header.
- Around line 120-124: Update collect_body to wrap the request body in
http_body_util::Limited before calling collect(), enforcing max_body_bytes
during reading; map a limit-exceeded error to DomainError::PayloadTooLarge while
preserving the existing validation error mapping for other read failures.
In `@gears/system/oagw/oagw/src/api/rest/router_tests.rs`:
- Around line 656-671: Update the tenant-isolation test around the `other`
`SecurityContext` and `router()` setup so the request executes with `other` as
its security context rather than the default `TENANT` context. Use the existing
router construction or helper mechanism to inject that context, and change the
response assertion to `StatusCode::NOT_FOUND` while preserving the request and
upstream ID.
In `@gears/system/oagw/oagw/src/api/rest/routes.rs`:
- Line 202: Update the OpenAPI registrations for the five proxied methods to use
a generic pass-through response instead of OperationBuilder::json_response,

- Line 89: Update SsrfPolicy::default to set enabled to true, then enforce the
policy by validating the resolved destination before both send() and the
WebSocket upgrade. Preserve allowed_hosts as the explicit exception for
permitted private destinations.
In `@gears/system/oagw/oagw/src/infra/plugin/oauth2_client_cred_auth.rs`:
- Around line 146-153: Update the validation guard in the OAuth2
client-credentials configuration flow to require exactly one of token_endpoint
or issuer_url: reject configurations where both are absent or both are present,
while preserving acceptance when only one is provided. Use the existing
token_endpoint and issuer_url values near the validation block.
- Around line 196-200: Update the TTL calculation in the OAuth2
client-credential token caching flow to avoid falling back to self.cache_ttl
when fetched.expires_in is shorter than margin; skip MemoryCache::put when
checked_sub yields no remaining lifetime, while preserving the existing
.min(self.cache_ttl) limit for longer-lived tokens.
- Around line 173-181: Enforce HTTPS for all OAuth endpoints in the plugin’s
configuration, OIDC discovery, and token-fetch flows: validate configured
token_endpoint and issuer_url URLs as HTTPS, configure discovery and token
requests with TransportSecurity::TlsOnly, and reject redirects whose targets are

operator-configured passthrough_allowlist with STRUCTURAL_HEADERS before calling
filter_headers, ensuring structural headers are always forwarded without
requiring operators to list them explicitly.
- Around line 63-69: Update strip_gateway_headers and the response-header
processing to parse every Connection header value, remove each nominated header
case-insensitively along with fixed hop-by-hop headers, and apply this shared
stripping after request rules and all response transformations. Add request and
response tests covering nominated fields.
In `@gears/system/oagw/oagw/src/infra/proxy/rate_limit.rs`:
- Around line 95-99: Bound the buckets map by adding idle-bucket eviction around
the entry handling in the rate-limiting logic. Remove entries whose last_refill
exceeds a small number of refill windows before inserting or retrieving the key,
while preserving existing token-bucket behavior for active clients. Use the
existing buckets, last_refill, and refill configuration symbols rather than
introducing unrelated changes.
In `@gears/system/oagw/oagw/src/infra/proxy/service.rs`:
- Around line 607-613: Update the WebSocket outbound-header construction in the
surrounding request-handling method to iterate over processed ctx.headers rather
than the original call.headers, preserving the existing exclusions and restoring
only the handshake headers required for the upgrade.
- Around line 544-545: Update the normal response path in the timeout handling
around Client::request and finalize_response so the configured proxy_timeout
remains enforced while the Incoming response body is read, not only until
response headers arrive. Apply the deadline to body reads and propagate expiry
as an error, while keeping WebSocket lifetime handling separate.
- Line 543: Update the request flow around self.client.request to apply
ssrf_policy before any connector or socket connection occurs. Resolve the
tenant-configured hostname, validate every resolved address against the policy,
and ensure the validated resolution is used to prevent DNS rebinding.
- Around line 346-350: Update select_endpoint to run check_scheme_admission on
the endpoint actually selected by X-OAGW-Target-Host or round-robin, rather than
validating only endpoints.first(). Preserve the existing allow_http_upstream
setting and return the selected endpoint only after validation succeeds.
- Around line 219-227: Update the request flow around run_plugins and forward to
reject credential-bearing requests whose upstream endpoint is plaintext HTTP
when allow_http_upstream is enabled. Require HTTPS for plugins that inject API
keys or OAuth bearer tokens, while preserving non-credential HTTP requests and
existing error handling through error_response.

per-tenant lock for alias validation, existence checks, inserts, and deletes.
Ensure concurrent inserts cannot create duplicate aliases and concurrent deletes
cannot invalidate a preceding contains_key check; apply the locking consistently

Minor comments:
In `@gears/system/oagw/oagw/src/api/rest/error.rs`:
- Around line 79-84: Update not_implemented and its problem_response
construction so the response body and HTTP status both consistently represent
501 Not Implemented; avoid building the body from DomainError::Validation, and
use a shared status source or dedicated DomainError variant while preserving the
existing response structure.
- Line 24: Update the problem-response construction around the detail insertion
to use error.title() when error.status().is_server_error(), while preserving
error.to_string() for 4xx responses with client-actionable validation details.
In `@gears/system/oagw/oagw/src/api/rest/handlers/management.rs`:
- Line 88: Update the handlers using Path<Uuid> extractors at the referenced
locations so malformed UUID rejections are converted into the existing
problem_response format, including application/problem+json and
X-OAGW-Error-Source. Apply the same rejection handling consistently across all
nine affected handlers, without relying on a router-level rejection mapper.
In `@gears/system/oagw/oagw/src/domain/alias.rs`:
- Line 196: Update common_registrable_suffix to return None when the hostname
slice is empty, before indexing roots[0]. Preserve the existing suffix
computation for non-empty inputs and ensure compute_derived_alias continues to
receive the same behavior.
In `@gears/system/oagw/oagw/src/domain/alias/alias_tests.rs`:
- Around line 303-304: Update the test setup around upstream and new so the old
endpoint remains an IP address while the new endpoint uses the hostname-derived
alias expected by the transition scenario. Reuse an existing matching alias
rather than constructing another unrelated alias, and preserve the rest of the
test behavior.
In `@gears/system/oagw/oagw/src/domain/gts_helpers.rs`:
- Around line 79-81: Update DomainError::instance_id() so CircuitBreakerOpen
maps to ERR_CIRCUIT_BREAKER_OPEN and PluginNotFound maps to ERR_PLUGIN_NOT_FOUND
instead of ERR_LINK_UNAVAILABLE, preserving the dedicated RFC 9457 type
identifiers used by problem_body.
In `@gears/system/oagw/oagw/src/domain/model.rs`:
- Line 598: Update the domain Plugin field plugin_type with the serde rename
needed to serialize it as type in PluginResponse, while preserving
PluginRequest’s existing inbound type mapping and the create, list, and get
response behavior.
- Around line 669-672: Update validate_cors to accept only HTTP/HTTPS origins
with a host, no credentials, and no path, query, or fragment before storing the
CORS configuration; preserve the existing invalid-origin DomainError behavior.
In `@gears/system/oagw/oagw/src/domain/services/management.rs`:
- Around line 739-743: `strictest` in `management.rs` is picking the wrong
policy when two limits have equal capacity because the `min_by` tie-break in the
comparator is reversed. Update the comparator inside `strictest` so equal
`capacity()` values prefer the lower `sustained.rate` instead of the higher one,
keeping the existing capacity ordering and the rest of the selection logic
unchanged.
In `@gears/system/oagw/oagw/src/infra/plugin/apikey_auth.rs`:
- Around line 85-89: Validate the placement value resolved from
config.string("in") or config.string("placement") before branching in the
API-key authentication flow. Accept case-insensitive "header" and "query" only,
and return DomainError::Validation for any other value instead of defaulting
unsupported values to the header branch; preserve the existing query and header
handling for valid values.
In `@gears/system/oagw/oagw/src/infra/plugin/request_id_transform.rs`:
- Line 30: Update the request ID selection around existing and Uuid::new_v4 so
blank inbound X-Request-ID values are treated as absent, then generate a UUID
fallback; preserve non-blank inbound IDs unchanged.
In `@gears/system/oagw/oagw/src/infra/proxy/auth_plugin_tests.rs`:
- Around line 200-203: Update the mock setup in the relevant auth plugin test to
retain the mock handle, then call its assert_calls(0) method after the existing
response assertions to verify that a missing secret prevents the upstream
request and forwarding.
In `@gears/system/oagw/oagw/src/infra/proxy/cors.rs`:
- Line 121: Update the CORS response header handling to use HeaderMap::append
for VARY instead of insert, preserving any upstream Vary values while adding
Origin.
In `@gears/system/oagw/oagw/src/infra/proxy/websocket_tests.rs`:
- Line 217: Wrap the socket read operations in the websocket test helpers,
including the reads near both referenced locations, with tokio::time::timeout
using an appropriate deadline. Propagate or assert the timeout result so stalled
connections produce a bounded test failure while preserving the existing
successful-read handling.

Nitpick comments:
In `@gears/system/oagw/oagw/src/api/rest/handlers/management.rs`:
- Around line 76-79: Update the list handlers, including the visible handler and
list_routes and list_plugins, to compute items.len() before constructing the
response, then move items into ListResponse::new instead of cloning the
collection. Preserve the existing status and response behavior.
In `@gears/system/oagw/oagw/src/infra/proxy/service_tests.rs`:
- Around line 1165-1166: Update the test request in the empty-alias case to pass
"/" or an empty string to get, rather than "/proxy/". Keep the assertion that
the response is NOT_FOUND, so the test exercises an empty alias instead of
duplicating unknown_alias_is_a_404_problem.

If the ingress preserves a caller-supplied header, the caller can vary this value and obtain a new bucket per request.

Run the request with the other tenant context.
This test constructs other but never attaches it to the request or router. The request still uses the original TENANT context from router(). The StatusCode::OK assertion therefore verifies same-tenant access, not tenant isolation.
Build the router with other, or add a router helper that accepts a SecurityContext. Then expect StatusCode::NOT_FOUND.

Keep the timeout active while the normal response body streams.
Client::request completes after the response head arrives. finalize_response then returns Incoming as an unrestricted streaming body. An upstream can send headers and stall the body indefinitely, despite the documented whole-request timeout.
Apply the deadline to normal response-body reads and propagate timeout errors. Keep WebSocket lifetime handling separate.

Build WebSocket headers from the processed request context.
run_plugins and the configured request-header rules modify ctx.headers. This branch instead copies the original call.headers. WebSocket upstream authentication, header transforms, and configured header removal therefore have no effect.
Build from ctx.headers and then restore only the handshake headers required for the upgrade.

Serialize per-tenant check-and-write operations.
MemoryUpstreamRepository::insert checks UpstreamTable::by_id and inserts in separate operations, so concurrent inserts can create duplicate aliases. Both update methods also separate contains_key from insert; a concurrent delete can therefore be followed by recreation. Protect these checks and mutations, including deletes, with the same per-tenant lock or an atomic alias index.

Propagate the request SecurityContext to credential lookups
The built-in API-key and OAuth2 plugins resolve secrets with SecurityContext::anonymous(). CredStoreClientV1::get therefore evaluates the nil tenant and subject, so tenant-scoped credentials return Ok(None) and valid proxy authentication fails. Pass the request context through the plugin execution path and use it for both credential lookups.
