Jenkins 2.274 and earlier, LTS 2.263.1 and earlier does not escape notification bar response contents (typically shown after form submissions via Apply button).
This results in a cross-site scripting (XSS) vulnerability exploitable by attackers able to influence notification bar contents.
Jenkins 2.275, LTS 2.263.2 escapes the content shown in notification bars.
