{"id":"CVE-2026-62371","published":"2026-09-21T17:17:37.150","lastModified":"2026-09-24T21:19:05.340","description":"KubeEdge is an open source system for extending native containerized application orchestration capabilities to hosts at Edge. From 1.12.0 until 1.21.2, 1.22.2, and 1.23.1, the v1alpha2 NodeUpgradeJob handler in edge/pkg/taskmanager/actions/nodeupgradejob.go concatenates authenticated user-controlled spec.version and spec.image values into the keadm upgrade edge shell command. A user with permission to create or update NodeUpgradeJob resources can supply shell metacharacters in either field, causing arbitrary commands to execute on targeted edge nodes with the privileges of the upgrade process and compromising node confidentiality, integrity, and availability. This issue is fixed in versions 1.21.2, 1.22.2, and 1.23.1.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-78"],"vendors":[],"products":[],"references":[{"url":"https://github.com/kubeedge/kubeedge/blob/master/CHANGELOG/CHANGELOG-1.21.md","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/blob/master/CHANGELOG/CHANGELOG-1.22.md","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/blob/master/CHANGELOG/CHANGELOG-1.23.md","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/commit/552af457a4c7ce80ea1678ab5889f475b36ea103","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/commit/657b745bebcdd7a221eb34c0aac13231ef12c37f","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/commit/b72db7f8a0f7be23261b4349eab33024b2007df0","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/pull/7028","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/pull/7029","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/pull/7030","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/releases/tag/v1.21.2","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/releases/tag/v1.22.2","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/releases/tag/v1.23.1","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/security/advisories/GHSA-5jpj-293f-rhvj","tags":[]}],"exploitRefs":[{"url":"https://github.com/kubeedge/kubeedge/blob/master/CHANGELOG/CHANGELOG-1.21.md","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/blob/master/CHANGELOG/CHANGELOG-1.22.md","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/blob/master/CHANGELOG/CHANGELOG-1.23.md","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/commit/552af457a4c7ce80ea1678ab5889f475b36ea103","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/commit/657b745bebcdd7a221eb34c0aac13231ef12c37f","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/commit/b72db7f8a0f7be23261b4349eab33024b2007df0","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/pull/7028","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/pull/7029","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/pull/7030","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/releases/tag/v1.21.2","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/releases/tag/v1.22.2","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/releases/tag/v1.23.1","tags":[]},{"url":"https://github.com/kubeedge/kubeedge/security/advisories/GHSA-5jpj-293f-rhvj","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw allows an attacker with permission to create or update NodeUpgradeJob resources to inject shell metacharacters, leading to arbitrary command execution with the privileges of the upgrade process.","exploitability":"Exploitation requires an attacker to have permission to create or update NodeUpgradeJob resources and knowledge of the affected fields.
