Jenkins LDAP Plugin 807.v7d7de30930cf and earlier follows LDAP referrals from the configured LDAP server. These can forward to an RMI URL that causes Jenkins to deserialize attacker-controlled data, resulting in Remote Code Execution (RCE) on the Jenkins controller if deserialization "gadgets" are available on the classpath. This allows attackers able to control the configured LDAP server, or able to perform a machine-in-the-middle attack, to execute code on the Jenkins controller. LDAP Plugin 807.809.vd3a_4e5e4ec98 no longer follows LDAP referrals.
Update org.jenkins-ci.plugins:ldap to 807.809.vd3a if you use the affected versions. Test the change in a non-production environment first.

AI coding agents often install or upgrade packages automatically in maven. A medium vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
