{"id":"CVE-2020-28914","details":"An improper file permissions vulnerability affects Kata Containers prior to 1.11.5. When using a Kubernetes hostPath volume and mounting either a file or directory into a container as readonly, the file/directory is mounted as readOnly inside the container, but is still writable inside the guest. For a container breakout situation, a malicious guest can potentially modify or delete files/directories expected to be read-only.","modified":"2026-04-10T04:25:48.703311Z","published":"2020-11-17T22:15:12.387Z","references":[{"type":"ADVISORY","url":"https://github.com/kata-containers/runtime/releases/tag/1.12.0"},{"type":"ADVISORY","url":"https://github.com/kata-containers/kata-containers/pull/1062"},{"type":"ADVISORY","url":"https://github.com/kata-containers/runtime/pull/3042"},{"type":"ADVISORY","url":"https://github.com/kata-containers/runtime/pull/3051"},{"type":"ADVISORY","url":"https://github.com/kata-containers/runtime/releases/tag/1.11.5"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kata-containers/kata-containers","events":[{"introduced":"0"},{"fixed":"797b6ad65ddd185bb91bb7faf7dca65fb00ae0b6"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"1.11.5"}]}},{"type":"GIT","repo":"https://github.com/kata-containers/runtime","events":[{"introduced":"0"},{"fixed":"28598666af4ca4855cc81a9bf829efb9e739b962"},{"fixed":"439d131e706e18018094bca48ae20adfa5d0fb7a"}]}],"versions":["0.0.1","0.2.0","0.3.0","1.0.0","1.1.0","1.10.0-alpha0","1.10.0-alpha1","1.10.0-rc0","1.11.0","1.11.0-alpha0","1.11.0-alpha1","1.11.0-rc0","1.11.1","1.11.2","1.11.3","1.11.4","1.12.0-alpha0","1.12.0-alpha1","1.12.0-rc0","1.2.0","1.3.0","1.3.0-rc0","1.3.0-rc1","1.4.0","1.5.0","1.5.0-rc1","1.5.0-rc2","1.6.0-rc1","1.6.0-rc2","1.7.0","1.7.0-alpha0","1.7.0-alpha1","1.7.0-rc1","1.8.0-alpha0","1.8.0-alpha1","1.8.0-alpha2","1.8.0-rc0","1.9.0-alpha0","1.9.0-alpha1","1.9.0-alpha2","1.9.0-rc0","1.9.3","20191207"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-28914.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H"}]}
