{"id":"ALPINE-CVE-2023-2728","details":"Users may be able to launch containers that bypass the mountable secrets policy enforced by the ServiceAccount admission plugin when using ephemeral containers. The policy ensures pods running with a service account may only reference secrets specified in the service account’s secrets field. Kubernetes clusters are only affected if the ServiceAccount admission plugin and the `kubernetes.io/enforce-mountable-secrets` annotation are used together with ephemeral containers.","modified":"2026-11-03T06:32:58.945514216Z","published":"2023-07-03T21:15:09.557Z","upstream":["CVE-2023-2728"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2023-2728"}],"affected":[{"package":{"name":"k3s","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/k3s?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.27.3.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-2728.json"}},{"package":{"name":"k3s","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/k3s?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.27.3.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-2728.json"}},{"package":{"name":"k3s","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/k3s?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.27.3.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-2728.json"}},{"package":{"name":"k3s","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/k3s?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.27.3.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-2728.json"}},{"package":{"name":"k3s","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/k3s?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.27.3.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-2728.json"}},{"package":{"name":"k3s","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/k3s?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.27.3.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-2728.json"}},{"package":{"name":"k3s","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/k3s?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.27.3.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-2728.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N"}]}
