Attackers can inject shell metacharacters or newline characters into unsanitized user-supplied values such as hostnames and hostspecs to execute arbitrary commands under the privileges of the rsync process or the invoking user.","published":"2026-08-13T15:19:43.200","modified":"2026-08-13T15:19:43.200","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/RsyncProject/rsync/releases/tag/v3.5.0"},{"type":"WEB","url":"https://github.com/RsyncProject/rsync/security/advisories/GHSA-5hcf-7xxm-rmqq"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/rsync-command-injection-via-multiple-code-paths"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-13T15:19:43.200"}}
