Azure Container Service Plugin 1.0.1 and earlier does not configure its YAML parser to prevent the instantiation of arbitrary types. This results in a remote code execution (RCE) vulnerability exploitable by users able to provide YAML input files to Azure Container Service Plugin’s build step.
Azure Container Service Plugin 1.0.2 configures its YAML parser to only instantiate safe types.
