A flaw was found in Jenkins versions prior to 2.251 and LTS 2.235.3.

Description msiddiqu 2020-09-03 05:00:16 UTC 
Jenkins 2.251 and earlier, LTS 2.235.3 and earlier does not escape the remote address of the host starting a build via 'Trigger builds remotely'. This results in a stored cross-site scripting (XSS) vulnerability exploitable by users with Job/Configure permission or knowledge of the Authentication Token.
