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.

- GHSA-79hx-3fp8-hj66DragonFly vulnerable to arbitrary file read and write on a peer machine2025-09-17ghsa · osvUS
### Impact A peer exposes the gRPC API and HTTP API for consumption by other peers. These 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. ```golang file, err := os.OpenFile(t.DataFilePath, os.O_RDWR, defaultFileMode) if err != nil { return 0, err } defer file.Close() if _, err = file.Seek(req.Range.Start, io.SeekStart); err != nil { return 0, err } n, err := io.Copy(file, io.LimitReader(req.Reader, req.Range.Length)) ``` ### Patches - Dragonfy v2.1.0 and above. ### Workarounds There are no effective workarounds, beyond upgrading. ### References A third party security audit was performed by Trail of Bits, you can see the [full report](https://github.com/dragonflyoss/dragonfly/blob/main/docs/security/dragonfly-comprehensive-report-2023.pdf).
