the edit permission and therefore the rights to do so. An attacker who can login to Bamboo as a user without the
edit permission for deployment projects is able to use this vulnerability, provided there is an existing plan
with a green build, to create a deployment project and execute arbitrary code on an available Bamboo Agent. By
default a local agent is enabled this means that code execution can occur on the system hosting Bamboo as the user
running Bamboo.");
