{"id":"CVE-2026-35350","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-35350","summary":"uutils coreutils doesn't properly handle setuid and setgid bits when ownership preservation fails","details":"The cp utility in uutils coreutils fails to properly handle setuid and setgid bits when ownership preservation fails. When copying with the -p (preserve) flag, the utility applies the source mode bits even if the chown operation is unsuccessful. This can result in a user-owned copy retaining original privileged bits, creating unexpected privileged executables that violate local security policies. This differs from GNU cp, which clears these bits when ownership cannot be preserved.","published":"2026-04-22T18:31:45Z","modified":"2026-09-10T03:51:03.765658653Z","cvss":{"score":6.6,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:L"},"epss":{"score":0.00125,"percentile":0.02628,"asOf":"2026-08-13"},"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-2026-35350"},{"type":"WEB","url":"https://github.com/uutils/coreutils/issues/9750"},{"type":"PACKAGE","url":"https://github.com/uutils/coreutils"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T03:51:03.765658653Z"}}
