CVE-2025-68705Public exploitNetwork attack vector

Arbitrary file read via unchecked RPC path

Published Jan 7, 2026 · Updated Jan 7, 2026

Path traversal in RustFS 1.0.0-alpha.13 through 1.0.0-alpha.78 allows remote attackers to read files through a signed RPC request. The read_file_stream implementation joins the caller-controlled path to volume_dir and checks only length, without rejecting absolute paths or parent-directory segments. Exploitation requires network access, the RPC secret, a registered disk and volume, and exact file-size knowledge; successful requests read files accessible to the RustFS process.
