Description
In Jenkins GitHub Plugin versions 1.46.0 and earlier, the JavaScript that validates the "GitHub hook trigger for GITScm polling" feature improperly processes the current job URL.
This results in a stored cross-site scripting (XSS) vulnerability exploitable by non-anonymous attackers with Overall/Read permission.
GitHub Plugin 1.46.0.1 no longer processes the current job URL as part of JavaScript implementing validation of the feature "GitHub hook trigger for GITScm polling".
