2.387.1- Upgrade org.jenkins-ci.main:jenkins-core to this version or later
Description
Jenkins 2.393 and earlier, LTS 2.375.3 and earlier, and prior to LTS 2.387.1 prints an error stack trace on agent-related pages when agent connections are broken, potentially revealing information about Jenkins configuration that is otherwise inaccessible to attackers.
Jenkins 2.394, LTS 2.375.4, and LTS 2.387.1 does not display error stack traces when agent connections are broken.
Affected versions

How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
