Detailsinfo

A vulnerability, which was classified as critical, was found in Eclipse Che up to 7.122.0. Affected is an unknown part of the component che-machine-exec. The manipulation of the argument username/namespace with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The che-machine-exec service constructs a shell command by concatenating user-controlled input (the username and namespace fields from the /exec/init and /exec/config JSON endpoints) into a double-quoted sh -c "echo "..." > ..." invocation without any escaping. When che-machine-exec is run with authentication disabled (its default), any network-reachable attacker can achieve remote code execution in containers che-machine-exec is configured to access, via shell command substitution ($(...) or backticks).

The advisory is available at gitlab.eclipse.org. This vulnerability is traded as CVE-2026-114278 since 10/21/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 10/28/2026). This vulnerability is assigned to T1202 by the MITRE ATT&CK project.
