Jenkins Active Directory Plugin deserializes data from LDAP referrals without validation
GitHub lists this reviewed advisory for org.jenkins-ci.plugins:active-directory. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.

02 / Applicability
The affected context
Affected versions, configuration prerequisites and known exclusions are public. Confirm each one against the deployed service.
org.jenkins-ci.plugins:active-directory
source listed< 2.41.1
Jenkins Active Directory Plugin 2.41 and earlier follows LDAP referrals from the configured Active Directory server by default. 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 Active Directory server, or able to perform a machine-in-the-middle attack, to execute code on the Jenkins controller. Active Directory Plugin 2.41.1 no longer follows LDAP referrals by default. Administrators unable to update to a fixed version can start Jenkins with the Java system property `hudson.plugins.active_directory.referral.ignore` set to `true` to mitigate the vulnerability. Administrators of Jenkins controllers requiring following LDAP referrals can set the Java system property `hudson.plugins.active_directory.referral.ignore` to `false` to restore the previous behavior.
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
