Jenkins OpsGenie Plugin vulnerable to Cleartext Transmission of Sensitive Information

Jenkins OpsGenie Plugin 1.9 and earlier stores API keys unencrypted in its global configuration file com.opsgenie.integration.jenkins.OpsGenieNotifier.xml and in job config.xml files on the Jenkins controller as part of its configuration.

Additionally, they are transmitted in plain text as part of the respective configuration forms.

These API keys can be viewed by users with Item/Extended Read permission (job config.xml only) or access to the Jenkins controller file system (both).

As of publication of this advisory, there is no fix.
