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.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
