Jenkins before 2.107 and Jenkins LTS before 2.89.4 did not properly prevent
specifying relative paths that escape a base directory for URLs accessing
plugin resource files. This allowed users with Overall/Read permission to
download files from the Jenkins master they should not have access to. On
Windows, any file accessible to the Jenkins master process could be
downloaded. On other operating systems, any file within the Jenkins home
directory accessible to the Jenkins master process could be downloaded.
