CVE-2026-70460Public exploitNetwork attack vectorHinoki check available

Remote file access via trusted symlink traversal

Published Aug 13, 2026 · Updated Aug 13, 2026

Path traversal in Rsync Project rsync 2.3.3 through 3.4.4 allows remote attackers to access files outside a daemon module root. The operator-path resolver accepts peer-supplied --partial-dir or --backup-dir values and follows root- or daemon-owned symlink components beyond that root. A trusted in-module symlink must already exist; reachable files are limited to those beneath that link and accessible to the daemon euid, where they can be read, overwritten, renamed, or unlinked.
