Doc Type: If docs needed, set a value
Doc Text:
A flaw was found in Jenkins in versions prior to 2.251 and LTS 2.235.3. Tooltip values, which are not properly escaped, can be contributed by plugins and use user-specified values. This results in a potential stored cross-site scripting (XSS) vulnerability. This highest threat from this vulnerability is to data confidentiality and integrity.

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.
