Jenkins meliora-testlab Plugin allows attackers with file system access to Jenkins master to obtain API key

An exposure of sensitive information vulnerability exists in Jenkins meliora-testlab Plugin 1.14 and earlier in TestlabNotifier.java that allows attackers with file system access to the Jenkins master to obtain the API key stored in this plugin's configuration. Additionally, the API key was not masked from view using a password form field. As of version 1.15, the plugin stores the API Key encrypted in the configuration files on disk and no longer transfers it to users viewing the configuration form in plain text.
