A missing permission check in Jenkins GitLab Plugin 1.5.11 and earlier in the GitLabConnectionConfig#doTestConnection form validation method allowed attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.
