rsync < 3.5.0 Path Traversal via Symlink Module Root
CVE-2026-53784 is fixed in 5 products on 1 platform, first by RHSA-2026:67463, released August 13, 2026. It is not reported as exploited. Patch Radar priority: High.
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 than the intended module root, enabling unauthorized file access.
