CVE-2026-82231

A Thrift client in Apache bRPC (version < 1.18.0, built with WITH THRIFT which is off by default) can be crashed by the server peer it talks to. When the server returns a T EXCEPTION reply whose exception struct is malformed, the client decodes it without catching what Apache Thrift throws (TProtocolException, TTransportException or std::length error). The exception unwinds out of the bthread task function and the process calls std::terminate(), terminating the whole process along with every other in-flight RPC.

This is the client response path, so the adversary is the server peer, which THREAT MODEL.md treats as untrusted. It requires a WITH THRIFT build (off by default).
