Timeline

2026-09-02	first spoke of it: In Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, objects of types marked as storing their configuration in independent top-level configuration files in Jenkins (such as the global configuration and jobs) can appear as nested field values in user-submitted `config.xml` documents and subsequently handle HTTP requests via Stapler, resulting in remote code execution.

What it is to other things

affects	jenkins/jenkins NVD
made_by	jenkins NVD

In words only, so not counted until a person confirms one:

made_by	`jenkins_project` NVD says “Jenkins Project”
affects	`jenkins_project/jenkins` NVD says “Jenkins Project · Jenkins”

Every value, with what each source said and its receipt

Property Source Said Means here

Automatable

At least one of those steps needs a person.
