As written in the advisory (Markdown source, shown as plain text).

Only older releases of Jenkins are affected by this vulnerability. Jenkins 2.275 and newer, LTS 2.263.2 and newer include a protection preventing this from being exploitable. Jenkins Kiuwan Plugin 1.6.1 escapes affected parts of the error message in the form validation endpoint.
