What does CVE-2026-53784 affect?
CVE-2026-53784 affects rsync daemon < 3.5.0, Unix/Linux systems running rsync in daemon mode, Systems with module root as a symlink and chroot disabled. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
What should I do about CVE-2026-53784?
Upgrade to rsync 3.5.0+, enable chroot or avoid symlinked module roots.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.

Patch when possible
- affected<= 3.4.4
As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
