Medium (5.9) in jenkins active directory. EPSS 0.5% chance of exploitation in the next 30 days. Fixed in org.jenkins-ci.plugins:active-directory 2.30.1.
Jenkins Active Directory Plugin 2.30 and earlier ignores the "Require TLS" and "StartTls" options and always performs the connection test to Active directory unencrypted, allowing attackers able to capture network traffic between the Jenkins controller and Active Directory servers to obtain Active Directory credentials.
