High [CVE-2026-53784] Unauthorized File Access via Symlink Module Root
CVE-2026-53784Source published Source updated
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. A flaw was found in rsync. This is an Important flaw. The rsync daemon is vulnerable to unauthorized file access via path traversal when configured with a symlinked module root and the `use chroot` option is explicitly disabled. This configuration is not default, but if present, a…

- Mitigation guidance
- To mitigate this vulnerability, ensure that the `use chroot` option is enabled in the rsync daemon configuration. If `use chroot` cannot be enabled, avoid using symlinks as the module root path or any of its components in the rsync daemon configuration. After modifying the rsync configuration, restart the rsync service for the changes to take effect.
