A flaw was found in jenkins in versions prior to 2.244 and versions prior to LTS 2.235.1. Job names in the 'Keep this build forever' badge tooltip are not properly escaped which results in a stored cross-site scripting (XSS) vulnerability exploitable by users able to configure job names.

Description Pedro Sampaio 2020-07-15 20:37:03 UTC 
Jenkins 2.244 and earlier, LTS 2.235.1 and earlier does not escape the job name in the 'Keep this build forever' badge tooltip. This results in a stored cross-site scripting (XSS) vulnerability exploitable by users able to configure job names.
