Description Pedro Sampaio 2020-07-15 20:38:42 UTC
Jenkins 2.244 and earlier, LTS 2.235.1 and earlier does not escape the href attribute of links to downstream jobs displayed in the build console page. This results in a stored cross-site scripting (XSS) vulnerability exploitable by users with Job/Configure permission.
