CVE-2026-114278: Eclipse Che che-machine-exec command injection vulnerability

CVE-2026-114278 · Severity: critical · CVSS 9.8 · Published 2026-10-28

Eclipse Che's machine-exec service is a component that executes commands in containers as part of the Eclipse Che development environment platform. When running with authentication disabled (the default configuration), an attacker on the network can inject arbitrary shell commands through user input fields, achieving complete remote code execution in any container the service manages. This could allow an attacker to access, modify, or delete all data and workspaces on the platform.

Technical details

The vulnerability is an OS command injection (CWE-78) in the /exec/init and /exec/config endpoints of che-machine-exec, where username and namespace parameters are concatenated directly into a shell command string without escaping. An unauthenticated attacker with network access can exploit this via shell metacharacters ($(...) or backticks) to break out of the double-quoted context and execute arbitrary commands. The fix validates these parameters to prevent command injection.
