Jenkins Cross-Site Scripting vulnerability in help icons
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
Jenkins 2.251 and earlier, LTS 2.235.3 and earlier does not escape the tooltip content of help icons. Tooltip values can be contributed by plugins, some of which use user-specified values. This results in a stored cross-site scripting (XSS) vulnerability. Jenkins 2.252, LTS 2.235.4 escapes the tooltip content of help icons.
