          "details": "CVE-2026-43619 is limited to rsync daemon deployments explicitly configured with “use chroot = no” (a non-default setting) and requires a local attacker with high privileges who already has write access to the exported module to win a brief symlink race; rsync over SSH and chrooted daemons are not exposed. Given the AV:L/PR:H scope and the need for this specific server-side configuration, the practical risk to centrally managed enterprise VM/server environments is low and this can be safely deprioritized relative to remotely exploitable issues.",
