Description
Yaml Axis Plugin 0.2.0 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 configure a multi-configuration (Matrix) job, or control the contents of a previously configured job’s SCM repository.
Yaml Axis Plugin 0.2.1 configures its YAML parser to only instantiate safe types.
