Details

Open redirect vulnerability in Jenkins CAS Plugin Jenkins CAS Plugin 1.6.0 and earlier improperly determines that a redirect URL after login is legitimately pointing to Jenkins. This allows attackers to perform phishing attacks by having users go to a Jenkins URL that will forward them to a different site after successful authentication. Jenkins CAS Plugin 1.6.1 only redirects to relative (Jenkins) URLs.
