{"schema":"threatline.record/2","record":{"id":"CVE-2026-82231","aliases":[],"summary":"Apache bRPC: Malformed Thrift T_EXCEPTION reply causes process termination in Thrift client","details":"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.\n\nThis 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).\n\nHow to Fix:\n1. Upgrade bRPC to version 1.18.0, which fixes this issue.\n2.
