**Issue Evaluation** Category: `type/bug` | Status: **Confirmed** The reported issue has been verified against the current codebase on the `develop` branch. **Root Cause:** `Http2ProtocolProxyHandler.match(ByteBuf in)` calls `in.getInt(in.readerIndex())` without first checking `in.readableBytes() >= 4`. When the protocol detector receives a buffer with fewer than 4 readable bytes, Netty throws `IndexOutOfBoundsException` instead of returning `false` to wait for more data. **Impact:** Proxy remoting/gRPC ingress path — short or fragmented buffers can crash the protocol detection pipeline. **Severity:** medium A fix proposal can be generated.
