  - An information exposure vulnerability in AboutJenkins.java, ListPluginsCommand.java that allows users with Overall/Read access to enumerate all installed plugins. (CVE-2018-1000192)

  - An improper neutralization of control sequences vulnerability in HudsonPrivateSecurityRealm.java that allows users to sign up using user names containing control characters
that can then appear to have the same name as other users, and cannot be deleted via the UI. (CVE-2018-1000193)

  - A path traversal vulnerability in FilePath.java, SoloFilePathFilter.java that allows malicious agents to read and write arbitrary
files on the Jenkins master, bypassing the agent-to-master security subsystem protection. (CVE-2018-1000194)

  - A server-side request forgery vulnerability in ZipExtractionInstaller.java that allows users with Overall/Read permission to have
Jenkins submit a HTTP GET request to an arbitrary URL and learn whether the response is successful (200) or not. (CVE-2018-1000195)");
