Description Pedro Sampaio 2020-07-15 20:33:19 UTC

Jenkins 2.244 and earlier, LTS 2.235.1 and earlier does not escape the upstream job’s display name shown as part of a build cause. This results in a stored cross-site scripting (XSS) vulnerability exploitable by users with Job/Configure permission.
