CVE-2026-70460 · rsync 2.3.3 < 3.5.0 Path Traversal via --partial-dir/--backup-dir Symlink

This page contains facts from public vulnerability sources. Check the original advisory before updating.

rsync 2.3.3 before 3.5.0 contains a path traversal vulnerability that allows a malicious sender to escape the module root by exploiting symlinks within the module file tree when using --partial-dir or --backup-dir options. Attackers with write access to place a symlink under the module root, or who can exploit a pre-existing trusted symlink, can direct file writes to locations outside the intended module root, achieving arbitrary file write relative to the module root parent.
