This bug was correctly reported, since flatbuffers does bundle some grpc sources from a vulnerable version. While I was not able to determine which specific grpc upstream changes fix this CVE, flatbuffers bundles only a few generator sources and headers from src/compiler/, and none of these contain hpack implementation code. Furthermore, only the build-time test executables link the system-wide grpc package. Based on that analysis, I am satisfied that flatbuffers is unaffected by CVE-2023-32732.
