Priority: ➖ Normal

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 6a676

This change introduces a new API gateway whose management endpoints can be read, replaced, and deleted without an authorization check, whose outbound dialing does not honor the configured SSRF restrictions, and whose rate-limit and CORS inheritance rules do not behave as documented. API-key authentication cannot succeed as wired, and streaming and WebSocket proxying lack response guards and timeouts. These issues should be resolved before merge.

Reject a bound plugin object that omits config.

{"plugin_ref":"..."} currently becomes a null binding. The proxy then filters out the null value and silently uses the persisted plugin configuration.

Require config in the object form. Callers that want record-level configuration can use the documented string form.

Proposed fix
-                    config: config.unwrap_or(serde_json::Value::Null),

+                        .ok_or_else(|| serde::de::Error::missing_field("config"))?,

Based on learnings: required serde fields must not use defaults that mask missing data.

Replace the upstream rate limit when route override is permitted.

merge keeps the most restrictive values. It does not implement the documented route-over-upstream override.

For example, an upstream rate of 10 and a route rate of 100 still produce 10 when the upstream sharing mode permits the override. Replace config.rate_limit with route_limit on this branch. Add a regression test with a more lenient route limit and a different scope.

Proposed fix
-            match &mut config.rate_limit {
-                Some(existing) => existing.merge(&route_limit),
-                None => config.rate_limit = Some(route_limit),
-            }
+            config.rate_limit = Some(route_limit);

set_header and add_header are case-sensitive, so duplicate header entries survive.

header() on line 100 and remove_header() on line 116 both normalise the name. set_header and add_header insert under the caller-supplied casing. Two entries therefore co-exist when two plugins write the same header with different casing, and the doc claim "replacing any existing entries" holds only for an exactly-matching key.

Concrete path: an AuthPlugin calls set_header("Authorization", initial), then a later TransformPlugin calls set_header("authorization", refreshed). The map keeps both keys. header("authorization") returns the Authorization entry, because uppercase bytes sort first in the BTreeMap, so the proxy reads the stale credential, and the outbound request can carry two conflicting Authorization headers. The test on lines 239-248 uses one casing for every write, so it does not detect this.

Normalise the key on every write. Lookups then also become O(log n) without a per-call allocation.

🐛 Proposed fix
 impl RequestContext {
     /// Reads the first value of a header, case-insensitively.
     pub fn header(&self, name: &str) -> Option<&str> {
-        let lower = name.to_ascii_lowercase();
-        self.headers.iter().find(|(k, _)| k.to_ascii_lowercase() == lower).and_then(|(_, v)| v.first().map(|s| s.as_str()))
+        self.headers
+            .get(&name.to_ascii_lowercase())
+            .and_then(|v| v.first().map(|s| s.as_str()))
     }
 
     /// Sets a header to a single value, replacing any existing entries.
     pub fn set_header(&mut self, name: impl Into<String>, value: impl Into<String>) {
-        self.headers.insert(name.into(), vec![value.into()]);
+        self.headers
+            .insert(name.into().to_ascii_lowercase(), vec![value.into()]);
     }
 
     /// Appends a value to a header.
     pub fn add_header(&mut self, name: impl Into<String>, value: impl Into<String>) {
-        self.headers.entry(name.into()).or_default().push(value.into());
+        self.headers
+            .entry(name.into().to_ascii_lowercase())
+            .or_default()
+            .push(value.into());
     }
 
     /// Removes a header, case-insensitively.
     pub fn remove_header(&mut self, name: &str) {
-        let lower = name.to_ascii_lowercase();
-        self.headers.retain(|k, _| k.to_ascii_lowercase() != lower);
+        self.headers.remove(&name.to_ascii_lowercase());
     }
 }

Apply the same change to ResponseContext::header and ResponseContext::set_header on lines 139-147, and to ErrorContext::set_header on lines 165-167. Update the test on line 245 to read ctx.headers.get("x-api-key"). Note that normalised keys change the casing of forwarded header names, so confirm the proxy transport restores canonical casing where an upstream requires it.

The WebSocket upgrade path applies no time bound.

read_handshake_reply (Line 428) loops on stream.read until it sees \r\n\r\n, reaches 64 KiB, or the peer closes. An upstream that accepts the connection and then sends nothing holds the handler task and the socket indefinitely. The 64 KiB cap never triggers for a silent peer.

The relay spawned at Lines 458-464 has the same property: copy_bidirectional runs until one side closes, with no idle bound.

state.config.proxy_timeout_secs exists. Apply it as a deadline around the handshake read, and apply an idle timeout to the relay so an abandoned upgraded connection is reclaimed.

The response-header removal assertion cannot fail.

The second mock at Lines 391-394 requires header_exists("x-unused"). The proxied request at Line 397 sends no headers, so that mock never matches. The first mock at Lines 366-369 answers instead, and it never sets x-upstream-note.

The assertion at Lines 406-409 therefore passes even if the remove rule is dropped entirely. Make the answering mock emit x-upstream-note, so the removal has a real target.

apply_filter ignores the requested field name.

parse_filter returns the field name, but apply_filter discards it as _field and always compares the value that field_of produces. In list_upstreams (handlers/upstreams.rs Line 103) field_of returns the alias. A caller sending $filter=id eq '<uuid>' therefore receives the upstreams whose alias equals that UUID, which is an empty page rather than the addressed resource.

The doc comment states that an unsupported expression filters nothing out. Compare the parsed field against the field the caller supports, and return the unfiltered list when the names differ.

The body stream never terminates after a read error.

On Err, the closure returns Some((Err(..), exchange)) and hands the unchanged exchange back to unfold. The next poll repeats the same failing read, so the stream yields errors indefinitely. A consumer that logs and continues instead of stopping at the first error spins without progress.

End the stream after the error.

Move DNS resolution off the Tokio worker thread.

OagwDataPlane::send calls synchronous UpstreamConnector::peer before its first .await. peer calls ToSocketAddrs::to_socket_addrs, so slow DNS can block the worker thread and delay other tasks.

Authorization Bypass

Reachability: External
Exploitability: Moderate
CWE: CWE-862 — Missing Authorization

Authorize all upstream operations.

get_upstream, list_upstreams, update_upstream, and delete_upstream call tenant-scoped control-plane methods that perform no authorization. Add the appropriate authorize and scope_allows_public checks before each operation. Otherwise, any authenticated tenant principal can read, replace, or delete that tenant’s upstream configuration.

In `@gears/system/oagw/oagw/src/api/rest/handlers/upstreams.rs` at line 85,
Authorize every upstream operation before invoking the tenant-scoped
control-plane methods: add the appropriate authorize and scope_allows_public
checks to the get_upstream, list_upstreams, update_upstream, and delete_upstream
handlers. Preserve the existing operation flow only after authorization
succeeds, including tenant scoping and current responses.

Sensitive Data Exposure

Exploitability: Moderate

Require HTTPS for configured OAuth URLs.

Reject non-HTTPS token_endpoint and issuer_url values. Allow HTTP only for explicit test or loopback configurations.
