{"id":"CVE-2026-35338","aliases":["GHSA-4c7q-4928-8445"],"url":"https://o3.security/vulnerability/CVE-2026-35338","summary":"uutils coreutils chmod Path Traversal Bypass of --preserve-root","details":"A vulnerability in the chmod utility of uutils coreutils allows users to bypass the --preserve-root safety mechanism. The implementation only validates if the target path is literally / and does not canonicalize the path. An attacker or accidental user can use path variants such as /../ or symbolic links to execute destructive recursive operations (e.g., chmod -R 000) on the entire root filesystem, leading to system-wide permission loss and potential complete system breakdown.","published":"2026-04-22T16:07:31.316Z","modified":"2026-08-05T03:32:04.532378002Z","cvss":{"score":7.3,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"uu_chmod","fixedVersion":"0.6.0"}],"fix":{"url":"https://github.com/uutils/coreutils/pull/10033","label":"uutils/coreutils#10033"},"references":[{"type":"WEB","url":"https://github.com/uutils"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35338.json"},{"type":"ADVISORY","url":"https://github.com/uutils/coreutils/releases/tag/0.6.0"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35338"},{"type":"FIX","url":"https://github.com/uutils/coreutils/pull/10033"},{"type":"PACKAGE","url":"https://github.com/uutils/coreutils"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-05T03:32:04.532378002Z"}}
