In multi-user environments, this introduces a brief window where a directory intended to be private is accessible to other users, potentially leading to unauthorized data access.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":3.3},"cwes":["CWE-367"],"references":["https://github.com/uutils/coreutils/pull/10036","https://github.com/uutils/coreutils/releases/tag/0.6.0"],"products":["uutils:coreutils"],"source":"nvd","synced_at":"2026-10-26T21:38:48.864438205+00:00"},"epss":{"cve":"CVE-2026-35353","score":0.00102,"percentile":0.00942,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-mj6p-44ch-cq69","url":"https://osv.dev/vulnerability/GHSA-mj6p-44ch-cq69","summary":"mkdir: -m exposes directory with umask perms before chmod (race window)","modified":"2026-07-06T20:41:29.914959Z","packages":[{"ecosystem":"crates.io","name":"uu_mkdir","purl":"pkg:cargo/uu_mkdir","ranges":["<0.6.0"],"fixed":["0.6.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
