Jenkins Mashup Portlets

Jenkins Mashup Portlets Plugin stored credentials unencrypted on the Jenkins master where they can be viewed by users with access to the master file system.

Jenkins Mashup Portlets Plugin 1.1.2 and earlier provides the "Generic JS Portlet" feature that lets a user populate a portlet using a custom JavaScript expression, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by authenticated attackers with Overall/Read permission.
