Description msiddiqu 2020-09-02 11:26:37 UTC

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.
