This issue occurs when files are being copied from a client to a server. During this process, the rsync server will send checksums of local data to the client to compare with in order to determine what data needs to be sent to the server.

          "details": "CVE-2024-12086 requires the rsync client to actively connect to an attacker‑controlled or compromised rsync server and hinges on a high‑complexity checksum‑oracle exchange during client‑to‑server syncing, not a passive drive‑by attack. The vulnerability only affects confidentiality and is constrained to files readable by the client process’s OS permissions; it provides no code execution, integrity change, or availability impact. In centrally managed environments that sync exclusively with authenticated, first‑party rsync endpoints, this precondition is absent, so it can be safely deprioritized.",
