Doc Text:
A path traversal and symlink vulnerability in rsync allows a malicious sender with write access to write files outside the intended directory. By exploiting symbolic links in conjunction with the --partial-dir or --backup-dir options, an attacker can bypass path restrictions to modify arbitrary system files, compromising system integrity

Description OSIDB Bzimport 2026-08-13 15:49:28 UTC 
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.
