CVE-2026-53797: Samba Rsync

Medium severity, CVSS 4.7. EPSS: 0.1% chance of exploitation in the next 30 days.

rsync before 3.5.0 contains a symlink race condition vulnerability in the sender's source tree traversal that allows an attacker who can manipulate a parent directory of the source tree to redirect file reads to unintended paths. Attackers can atomically replace a parent directory component with a symlink pointing outside the source root between path resolution and file open operations to disclose file contents outside the intended transfer root.
