DotCi Plugin 2.40.00 and earlier does not escape the GitHub user name parameter provided to commit notifications when displaying them in a build cause.
This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to submit crafted commit notifications to the `/githook/` endpoint (see also SECURITY-2867
