Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Jenkins LDAP Plugin 807.v7d7de30930cf and earlier, a Maven package org.jenkins-ci.plugins:ldap, follows LDAP referrals and can deserialize attacker-controlled data from an RMI URL. An attacker who controls the configured LDAP server, or can carry out a machine-in-the-middle attack, could execute code on the Jenkins controller if suitable deserialization gadgets are on the classpath. Upgrade to 807.809.vd3a or later, which no longer follows LDAP referrals.
