### Summary OpenTelemetry-Go Contrib has a [handler wrapper `otelhttp`](https://github.com/open-telemetry/opentelemetry-go-contrib/blob/5f7e6ad5a49b45df45f61a1deb29d7f1158032df/instrumentation/net/http/otelhttp/handler.go#L63-L65) that adds the following labels by deafult that have unbound cardinality: - `http.user_agent` - `http.method` This leads to the server's potential memory exhaustion when many malicious requests are sent to it. ### Details HTTP header User-Agent or HTTP method for requests can be easily set by an attacker to be random and long. The library internally uses [httpconv.ServerRequest](https://github.com/open-telemetry/opentelemetry-go/blob/v1.12.0/semconv/internal/v2/http.go#L159) that records every value for HTTP [method](https://github.com/open-telemetry/opentelemetry-go/blob/38e1b499c3da3107694ad2660b3888eee9c8b896/semconv/internal/v2/http.go#L204) and [User-Agent](https://github.com/open-telemetry/opentelemetry-go/blob/38e1b499c3da3107694ad2660b3888eee9c8b8...
OpenTelemetry-Go Contrib is a collection of third-party packages for OpenTelemetry-Go. A handler wrapper out of the box adds labels `http.user_agent` and `http.method` that have unbound cardinality. It leads to the server's potential memory exhaustion when many malicious requests are sent to it. HTTP header User-Agent or HTTP method for requests can be easily set by an attacker to be random and long. The library internally uses `httpconv.ServerRequest` that records every value for HTTP `method` and `User-Agent`. In order to be affected, a program has to use the `otelhttp.NewHandler` wrapper and not filter any unknown HTTP methods or User agents on the level of CDN, LB, previous middleware, etc. Version 0.44.0 fixed this issue when the values collected for attribute `http.request.method` were changed to be restricted to a set of well-known values and other high cardinality attributes were removed. As a workaround to stop being affected, `otelhttp.WithFilter()` can be used, but it requir...
A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive server resource consumption. While the total number of requests is bounded by the http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create a new request while the existing one is still executing. With the fix applied, HTTP/2 servers now bound the number of simultaneously executing handler goroutines to the stream concurrency limit (MaxConcurrentStreams). New requests arriving when at the limit (which can only happen after the client has reset an existing, in-flight request) will be queued until a handler exits. If the request queue grows too large, the server will terminate the connection. This issue is also fixed in golang.org/x/net/http2 for users manually configuring HTTP/2. The default stream concurrency limit is 250 streams (requests) per HTTP/2 connection. This value may be adjusted using the golang.org/x/net/http2 package; s...
