KubeEdge ConfigUpdateJob processing was vulnerable to command injection on edge nodes.
The updateFields values from a ConfigUpdateJob were concatenated into a command string and executed through a system shell. An authenticated user with sufficient permissions to create or update ConfigUpdateJob resources could include shell metacharacters in the supplied configuration fields and cause unintended commands to be executed on targeted edge nodes.
Successful exploitation could allow an authenticated attacker to execute arbitrary commands on affected edge nodes with the privileges of the KubeEdge process handling the ConfigUpdateJob.
The attacker must already have permission to create or modify ConfigUpdateJob resources and target an enrolled edge node.
The fix removes shell-based command construction and invokes keadm config-update using structured command arguments.
The complete --set value is passed as a single literal argument, preventing shell metacharacters from being interpreted as commands.
Fixes are planned for the following maintained releases:
Until a patched release is available:
