{"id":"CVE-2026-35351","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-35351","summary":"uutils coreutils doesn't preserve file ownership during moves across different filesystem boundaries","details":"The mv utility in uutils coreutils fails to preserve file ownership during moves across different filesystem boundaries. The utility falls back to a copy-and-delete routine that creates the destination file using the caller's UID/GID rather than the source's metadata. This flaw breaks backups and migrations, causing files moved by a privileged user (e.g., root) to become root-owned unexpectedly, which can lead to information disclosure or restricted access for the intended owners.","published":"2026-04-22T18:31:45Z","modified":"2026-09-10T03:51:01.367045573Z","cvss":{"score":4.2,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L"},"epss":{"score":0.00132,"percentile":0.03111,"asOf":"2026-09-13"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"coreutils","fixedVersion":null}],"fix":null,"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35351"},{"type":"WEB","url":"https://github.com/uutils/coreutils/issues/9714"},{"type":"PACKAGE","url":"https://github.com/uutils/coreutils"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T03:51:01.367045573Z"}}
