Jenkins GitLab Authentication Plugin 1.13 and earlier records the HTTP Referer header as part of the URL query parameters when the authentication process starts, allowing attackers with access to Jenkins to craft a URL that will redirect users to an attacker-specified URL after logging in.
The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.
