PatchTheCVECVE-2026-53784: rsync before 3.5.0 contains a path traversal vulnerability that allows remote clients to access files outside
CVE-2026-53784 is a high-severity flaw (CVSS 7.1) affecting rsync. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
rsync before 3.5.0 contains a path traversal vulnerability that allows remote clients to access files outside the intended module root when use chroot is disabled and the module root path or a component of it is a symlink. The daemon calls chdir() to the module root at session initialization without resolving symlinks via realpath() or equivalent, causing subsequent relative-path operations to reference files relative to the symlink target rather
