Description Sam Fowler 2018-01-29 01:18:21 EST 
Users with permission to create or configure agents in Jenkins could configure an EC2 agent to run arbitrary shell commands on the master node whenever the agent was supposed to be launched.

Configuration of these agents now requires the Run Scripts permission typically only granted to administrators.
