The vulnerability arises because the controller concatenates user-supplied values from the 'spec.version' and 'spec.image' fields directly into a shell string used to invoke 'keadm upgrade edge'. An attacker with the ability to create or update NodeUpgradeJob resources can inject shell metacharacters into these fields, resulting in arbitrary code execution on the target edge node with the privileges of the KubeEdge upgrade process. This issue represents a significant risk for deployments where API access is shared with untrusted entities, as it allows for container escape or host-level compromise of edge computing infrastructure.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker gains authenticated access to the KubeEdge cluster with permissions to manage NodeUpgradeJob resources.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious payload using shell metacharacters (e.g., ';', '\u0026amp;\u0026amp;', or '$()').\u003c/li\u003e\n\u003cli\u003eThe attacker submits an update or create request to the v1alpha2 API for a NodeUpgradeJob resource.\u003c/li\u003e\n\u003cli\u003eThe malicious shell metacharacters are embedded within the 'spec.version' or 'spec.image' YAML fields.\u003c/li\u003e\n\u003cli\u003eThe KubeEdge controller processes the resource and dynamically builds the upgrade command using shell-based concatenation.\u003c/li\u003e\n\u003cli\u003eThe system executes the resulting command string via the OS shell, triggering the payload.\u003c/li\u003e\n\u003cli\u003eThe injected code executes on the target edge node, granting the attacker arbitrary command execution capabilities.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-62371 grants authenticated attackers the ability to execute arbitrary commands on edge nodes.
