          "details": "Deprioritize: exploitation requires an attacker who already has local write access to a parent directory of the rsync source on the sender host and can win a narrow TOCTOU symlink race, a high‑complexity precondition that controlled rsync jobs using system‑owned source paths inherently prevent. The impact is limited to confidentiality (file reads) with no code execution, integrity change, or availability effect, and it confers no additional privileges beyond the attacker’s existing local access. In centrally managed server/VM environments where rsync operates over fixed, non‑writable source trees, the practical exploitability is negligible.",
