Short explanation
The che-machine-exec service in Eclipse Che concatenates user-controlled input from the /exec/init and /exec/config endpoints into shell commands without proper escaping. When authentication is disabled, a network-reachable attacker can achieve remote code execution.
Carrying a critical CVSS score of 9.8, this vulnerability allows unauthenticated remote code execution over the network against targeted containers, presenting severe risks to confidentiality, integrity, and availability.
What should be done?
- Follow official vendor advisories and updates
- Enable authentication for the che-machine-exec service
- Review and restrict network access controls
Chain of evidence and sources
Eclipse Che içindeki che-machine-exec servisi, doğrulanmamış girdileri sh -c çağrısına ekleyerek komut enjeksiyonuna zemin hazırlar.
Kimlik doğrulamanın devre dışı olduğu varsayılan yapılandırmada ağ üzerinden uzaktan kod çalıştırma mümkündür.
CVE-2026-114278 zafiyeti 9.8 taban CVSS puanına sahiptir ve kritik önem taşımaktadır.
Show the technical text from the sources
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).
