Description OSIDB Bzimport 2026-08-05 18:02:50 UTC
Jenkins 2.575 and earlier, LTS 2.568.1 and earlier does not restrict the types of objects that can be instantiated as part of the project naming strategy configuration, allowing attackers with Overall/Manage permission to instantiate arbitrary types related to configuration, including those intended for configuration only by administrators.
