Description Michael Kaplan 2021-02-04 13:50:01 UTC 
Jenkins 2.274 and earlier, LTS 2.263.1 and earlier does not escape display names and IDs of item types shown on the New Item page, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to specify display names or IDs of item types.
