[org.jenkins-ci.plugins:radargun] RCE vulnerability in RadarGun Plugin

RadarGun Plugin 1.7 and earlier does not configure its YAML parser to prevent the instantiation of arbitrary types. This results in a remote code execution vulnerability exploitable by users able to configure RadarGun Plugin’s build step.

RadarGun Plugin 1.8 configures its YAML parser to only instantiate safe types.
