This function does not perform any permission checks when a given directory path exists already. A possible workaround is to ensure the directories have the desired permission (700).","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","score":7.1},"cwes":["CWE-281"],"references":["https://github.com/etcd-io/etcd/security/advisories/GHSA-chh6-ppwq-jh92","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/L6B6R43Y7M3DCHWK3L3UVGE2K6WWECMP/","https://github.com/etcd-io/etcd/security/advisories/GHSA-chh6-ppwq-jh92","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/L6B6R43Y7M3DCHWK3L3UVGE2K6WWECMP/"],"products":["etcd:etcd","fedoraproject:fedora"],"source":"nvd","synced_at":"2026-10-19T21:06:22.076270124+00:00"},"epss":{"cve":"CVE-2020-15113","score":0.00218,"percentile":0.12349,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-chh6-ppwq-jh92","url":"https://osv.dev/vulnerability/GHSA-chh6-ppwq-jh92","summary":"Improper Preservation of Permissions in etcd","modified":"2026-09-10T03:50:09.439972373Z","packages":[{"ecosystem":"Go","name":"github.com/etcd-io/etcd","purl":"pkg:golang/github.com/etcd-io/etcd","ranges":[">=3.4.0-rc.0 <3.4.10"],"fixed":["3.4.10"]},{"ecosystem":"Go","name":"github.com/etcd-io/etcd","purl":"pkg:golang/github.com/etcd-io/etcd","ranges":["<3.3.23"],"fixed":["3.3.23"]}]}],"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).
