CVE-2017-1000091: Cross-Site Request Forgery (CSRF)

October 5, 2017 (updated October 17, 2017)

GitHub Branch Source Plugin connects to a user-specified GitHub API URL as part of form validation and completion. This functionality improperly checked permissions, allowing any user with Overall/Read access to Jenkins to connect to any web server and send credentials with a known ID, thereby possibly capturing them. Additionally, this functionality did not require POST requests be used, thereby allowing the above to be performed without direct access to Jenkins via Cross-Site Request Forgery.
