概要

Jenkins sets the Content-Security-Policy header to static files served by Jenkins (specifically DirectoryBrowserSupport), such as workspaces, /userContent, or archived artifacts, unless a Resource Root URL is specified.

NeuVector Vulnerability Scanner Plugin 1.20 and earlier globally disables the Content-Security-Policy header for static files served by Jenkins whenever the 'NeuVector Vulnerability Scanner' build step is executed. This allows cross-site scripting (XSS) attacks by users with the ability to control files in workspaces, archived artifacts, etc.

Jenkins instances with Resource Root URL configured are unaffected.

NVD の説明

Jenkins NeuVector Vulnerability Scanner Plugin 1.20 and earlier programmatically disables Content-Security-Policy protection for user-generated content in workspaces, archived artifacts, etc. that Jenkins offers for download.
