Path Traversal vulnerability in Jenkins Embeddable Build Status Plugin

Jenkins Embeddable Build Status Plugin 2.0.3 and earlier allows specifying a style query parameter that is used to choose a different SVG image style without restricting possible values, resulting in a relative path traversal vulnerability that allows attackers without Overall/Read permission to specify paths to other SVG images on the Jenkins controller file system.

Embeddable Build Status Plugin 2.0.4 restricts the style query parameter to one of the three legal values.
