Exposure of Sensitive Information to an Unauthorized Actor in Jenkins Kubernetes Plugin
Jenkins Kubernetes Plugin prior to 1.27.4, 1.26.5, 1.25.4.1, and 1.21.6 includes a feature to replace placeholders in pod template and container template fields with environment variable values.
This feature allows low-privilege users to access possibly sensitive Jenkins controller environment variables.
Kubernetes Plugin 1.27.4, 1.26.5, 1.25.4.1, and 1.21.6 disables this feature.
