Description Michael Kaplan 2020-11-09 14:11:05 UTC 
Kubernetes Plugin 1.27.3 and earlier 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.
