Summary

Dragonfly is an open source P2P-based file distribution and image acceleration system. Prior to 2.1.0, the gRPC API and HTTP APIs allow peers to send requests that force the recipient peer to create files in arbitrary file system locations, and to read arbitrary files. This allows peers to steal other peers’ secret data and to gain remote code execution (RCE) capabilities on the peer’s machine.This vulnerability is fixed in 2.1.0.
