File permissions for non-root users running in a privileged container are not correctly checked. This flaw can be abused by a low-privileged user inside the container to access any other file in the container, even if owned by the root user inside the container. It does not allow to directly escape the container, though being a privileged container means that a lot of security features are disabled when running the container. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.0},"cwes":["CWE-863"],"references":["https://bugzilla.redhat.com/show_bug.cgi?id=1915734","https://bugzilla.redhat.com/show_bug.cgi?id=1915734"],"products":["podman_project:podman","redhat:enterprise_linux","redhat:openshift_container_platform"],"source":"nvd","synced_at":"2026-10-19T21:14:10.479542811+00:00"},"epss":{"cve":"CVE-2021-20188","score":0.00261,"percentile":0.17941,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-9h63-7qf6-mv6r","url":"https://osv.dev/vulnerability/GHSA-9h63-7qf6-mv6r","summary":"Improper Authorization in github.com/containers/libpod","modified":"2024-08-21T15:41:50.958534Z","packages":[{"ecosystem":"Go","name":"github.com/containers/libpod","purl":"pkg:golang/github.com/containers/libpod","ranges":["<1.7.0"],"fixed":["1.7.0"]}]},{"id":"GO-2022-0641","url":"https://osv.dev/vulnerability/GO-2022-0641","summary":"Improper Authorization in github.com/containers/libpod","modified":"2026-03-03T04:50:47.899562Z","packages":[{"ecosystem":"Go","name":"github.com/containers/libpod","purl":"pkg:golang/github.com/containers/libpod","ranges":["<1.7.0"],"fixed":["1.7.0"]}]}],"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).
