CVE-2022-43432

描述

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. XFramium Builder Plugin 1.0.22 and earlier globally disables the `Content-Security-Policy` header for static files served by Jenkins as soon as it is loaded. 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](https://www.jenkins.io/doc/book/security/user-content/#resource-root-url) configured are unaffected.
