CVE-2026-29518 is a time-of-check to time-of-use race condition in rsync daemon file handling affecting versions before 3.4.3 when module chroot confinement is disabled. Path validation and file opening occur separately, allowing a local attacker with write access to a module directory to replace a parent directory component with a symbolic link between those operations. File operations can consequently escape the intended module boundary, enabling unauthorized file reads and arbitrary file creation or overwrite. Exploitation can lead to privilege escalation when the daemon runs with elevated privileges. Modules using the default enabled chroot configuration are not exposed to this escape path.
