| Package | Affected versions | Patched versions |
|---|---|---|
| org.jenkins-ci.plugins:xframium | ≤ 1.0.22 | |
| xframium builder | ≤ 1.0.22 |
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 configured are unaffected.
