How to fix?

Upgrade org.jenkins-ci.plugins:support-core to version 2.72.1 or higher.

Overview

org.jenkins-ci.plugins:support-core is a plugin that provides the basic infrastructure for generating "bundles" of support information within Jenkins.

Affected versions of this package are vulnerable to Information Exposure. Support Core Plugin provides the serialized user authentication as part of the "About user (basic authentication details only)" information. In some configurations, this can include the session ID of the user creating the support bundle. Attackers with access to support bundle content and the Jenkins instance could use this information to impersonate the user who created the support bundle.

Fixed versions of Support Core Plugin no longer provides the serialized user authentication as part of the "About user (basic authentication details only)" information. As a workaround, deselecting "About user (basic authentication details only)" before creating a support bundle will exclude the affected information from the bundle.
