Summary

gardenctl is a command-line client for the Gardener which configures access to clusters and cloud provider CLI tools. When using nonPOSIX shells such as Fish and PowerShell, gardenctl versions through 2.11.0 allow an attacker with administrative privileges for a Gardener project to craft malicious credential values. The forged credential values are used in infrastructure Secret objects that break out of the intended string context when evaluated in Fish or PowerShell environments used by the Gardener service operators.
