CVE-2026-62182 · Severity: high · CVSS 8.8 · Published 2026-09-21

KubeEdge is an edge computing platform that extends Kubernetes to edge devices. The ConfigUpdateJob feature, which manages configuration updates on edge nodes, is vulnerable to command injection when processing user-supplied configuration field values. An authenticated attacker with permission to create or modify configuration jobs can inject shell commands that execute with KubeEdge process privileges on targeted edge nodes, potentially compromising system integrity and availability.

**Am I affected by CVE-2026-62182?** Check whether you run github.com/kubeedge/kubeedge (Go) or KubeEdge at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## How to fix

- github.com/kubeedge/kubeedge (Go): upgrade to 1.21.2, 1.23.1 or later

  ```sh
  go get github.com/kubeedge/kubeedge@v1.23.1
  ```


## Technical details

The vulnerability is a command injection flaw in the ConfigUpdateJob processor that concatenates user-controlled `updateFields` values directly into a shell command string without proper sanitization or escaping. The vulnerable component executes the resulting command via a system shell, allowing attackers to inject shell metacharacters and execute arbitrary commands. The attack requires authentication and RBAC permissions to create or modify ConfigUpdateJob resources, and targets enrolled edge nodes. The fix replaces shell-based command construction with structured argument passing, preventing metacharacter interpretation. Patches are available or planned for v1.23.1, v1.22.2, and v1.21.2.

## Affected products

- KubeEdge KubeEdge before v1.23.1, v1.22.2, v1.21.2
