CVE-2018-6356: Path Traversal

February 20, 2018 (updated March 19, 2018)

Jenkins and Jenkins LTS does not properly prevent specifying relative paths that escape a base directory for URLs accessing plugin resource files. This allows 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.
